HDFS Append

Hi,
I have a use case to keep appending data to a HDFS file. Does someone know how we can append using Talend?
Thanks,

Re: HDFS Append

Hi sabrina, 
i am facing the same issue for the append functionality in HDFS output !! i have tried with two HDFS output writing to the same file and as well one HDFS output (appending) writing the file twice (in which i am iterating the job twice). is there any other way around for this ?
