HBASE-Write-No bytes written


HBASE-Write-No bytes written

Champion Alumni




I have a pig job that writes into HBase. However, from time to time, for a successful job, in the logs I have:



  Successfully read 2588027 records (1523635920 bytes) from: "my_database.my_table"
  Successfully stored 2588027 records in: "hdfs://StandbyNameNode/user/agherman/my_write_table"
  Total records written : 2588027
  Total bytes written : 0
  Spillable Memory Manager spill count : 0
  Total bags proactively spilled: 0
  Total records proactively spilled: 0


And when I have 

Total bytes written : 0

in fact, my data wasn't write. 



However, when I run the second time (the same job) this is sometimes working



Could you please let me know what this means?  what I could do to stop it ?

how could I identify that in fact the job wasn't working (besides checking that I have bytes written)



Thank you!
