HBase Bug or not ? pls give some advises.

CDH version: 5.9.0

 

i am tring to test HBase coprocessor like preget , preput ,preScannerOpen, i find there are someting is very strange.

 

1) the coprocessor will work find if the table has no any coprocessor .

 

2) but if i have modified the coprocessor and try to upload the new coprocessor to the HDFS, and to do the below setup:

 

alter 'test1' , METHOD => 'table_att_unset', NAME=> 'coprocessor$1'

alter 'test1' , METHOD => 'table_att', 'COPROCESSOR'=> 'hdfs://nameservice1/tmp/observeTrigger.jar|com.isesol.storm.observTrigger||'

 

it won't work fine, until i am going to drop the table, and set the coprocessor again.

 

who can tell me this is  bug or not ?  

 

 

thanks 

chris.
