Hello,

I'm having a coordinator that is executed every day that is writing in HBase tables.

Yesterday the job failed because:

12477375 [hconnection-0x17444a28-shared--pool954-t772] INFO org.apache.hadoop.hbase.client.AsyncProcess

I did the folowings checks:

- hbase hbck ==> no error

- hbase fsck / ==> no error

- major_compact 'table_name' ==> I managed to run the job

However, even if the workflow finished succesfully, there is no data wroto to hbase tables.

I tried:

- flush 'table_name' ==> didn't changed anything.

Do you have any suggestions on why the data is not wrote? 

(I tried the flush command because I supposed that the files are not written)
