Talend Version          6.3.1 Summary While running a job from TAC, you get the following error in the Job Server logs: [FATAL]: coe_s.emp_ff_to_ge_greenplum_load_upd_dev21_0_1.EMP_FF_to_GE_GREENPLUM_LOAD_UPD_DEV21 - tGEGreenplumGPLoad_1 gpload failed because: OSError: [Errno 13] Permission denied: '/root/gpAdminLogs' Additional Versions   Product Talend Data Integration Component tGEGreenplumGPLoad_1 Problem Description When you enable JobServer to run as a service in UNIX systems, you get the following error when using the tGEGreenplumGPLoad component. [FATAL]:coe_s.emp_ff_to_ge_greenplum_load_upd_dev21_0_1.EMP_FF_to_GE_GREENPLUM_LOAD_UPD_DEV21 - tGEGreenplumGPLoad_1 gpload failed because: OSError: [Errno 13] Permission denied: '/root/gpAdminLogs' Problem root cause If you run /etc/init.d/custom script as root, and even though you have your script configured to switch to the talend user using RUN_AS_USER, gpload expects the talend user to write under /root/gpAdminLogs. Since this directory is owned by root, it fails with the stated error. Even if you change the ownership of this particular directory to the talend user, it still fails with the same error. If you start the JobServer using the start_rs.sh script (default), this issue is not observed. Solution or Workaround Run the script that starts your Jobserver as a service using the following command: su -l talend -c "/etc/init.d/yourshscript.sh start" This should take care of the permission issues; if not, have a scripting engineer take a look at your script.   For more information on gpload, see the following page: https://kb.informatica.com/solution/23/Pages/54/336129.aspx.

Problem Description Studio logs output from the tLogRow component to the Run tab console, as shown below. But if you log too many statements, for example, more than 1,000 statements, Studio can slow down or hang.     Solution Log the Job output to a separate log file, by navigating to Studio > File > Edit Project properties > Log4j. Your Studio will look like this:     Create a FILE appender section and add the following lines: <!-- FILE appender --> <appender name="FILE" class="org.apache.log4j.FileAppender"> <param name="file" value="c:/temp/talend_job.log" /> <param name="append" value="false" /> <param name="threshold" value="debug" /> <layout class="org.apache.log4j.PatternLayout"> <!-- 'p' is Priority: INFO, DEBUG, TRACE, etc. --> <!-- 'c' is Category: fully qualified project and job name --> <!-- 'm' is Message: the message the component is logging --> <!-- 'n' is Line Separator: e.g. the newline character --> <param name="ConversionPattern" value="[%-5p]: %c - %m%n" /> <!-- <param name="ConversionPattern" value="%m%n" /> --> </layout> </appender> Notice that you can customize the output path, "file", for example, "c:/temp/talend_job.log".   Create an <appender-ref ref="FILE"/> section under the 'Root logger' section at the bottom: <!-- Root Logger --> <root> <priority value ="warn"/> <appender-ref ref="CONSOLE"/> <appender-ref ref="FILE"/> <!-- <appender-ref ref="LOGSTASH"/> --> </root> You will already have the CONSOLE appender section.   These sections of your file should look similar to this: <!-- CONSOLE appender --> <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender"> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="[%-5p]: %c - %m%n" /> </layout> </appender> ... <!-- FILE appender --> <appender name="FILE" class="org.apache.log4j.FileAppender"> <param name="file" value="c:/temp/talend_job.log" /> <param name="append" value="false" /> <param name="threshold" value="debug" /> <layout class="org.apache.log4j.PatternLayout"> <!-- 'p' is Priority: INFO, DEBUG, TRACE, etc. --> <!-- 'c' is Category: fully qualified project and job name --> <!-- 'm' is Message: the message the component is logging --> <!-- 'n' is Line Separator: e.g. the newline character --> <param name="ConversionPattern" value="[%-5p]: %c - %m%n" /> <!-- <param name="ConversionPattern" value="%m%n" /> --> </layout> </appender> ... <!-- Root Logger --> <root> <priority value ="warn"/> <appender-ref ref="CONSOLE"/> <appender-ref ref="FILE"/> <!-- <appender-ref ref="LOGSTASH"/> --> </root>   Open your Job. In the Run view, select the Advanced settings tab. Select the log4jLevel check box, and from the drop-down list, set the value to Debug.   Alternatives The following alternates redirect the console output to other places instead of creating a new place to output the information.   Alternate solution 1 As shown in this Community discussion forum thread, you can do this with a little Java code in a tJava component at the beginning of your Job. For example: java.io.File outputFile = new java.io.File("c:/temp/my_job_output.txt"); System.setOut(new java.io.PrintStream(new java.io.FileOutputStream(outputFile, true), true));   Alternate solution 2 If you do not want pure Java, tRedirectOutput is a custom component that is used to redirect all the messages printed on the console to a file.   Alternate solution 3 Uncomment and configure the logstash section of the Log4j settings by navigating to Studio > File > Edit Project properties > Log4j: <!-- logstash appender --> <!-- <appender name="LOGSTASH" class="org.apache.log4j.net.SocketAppender"> <param name="RemoteHost" value="localhost"/> <param name="Port" value="8052"/> </appender> -->
