What fix u tried now will help you. You can not avoid the loop by
using the complete or bypass way.. Because that is on the present
context. Another put on region will create a new context and so that
continues. One more thing/suggestion would be to see the hook
preBatchMutate. You will receiv
Hi
I overrode coprocessor prePut() function to prevent normal put, and
try to put the same data with different rowkey into the same table.
The code is "context.getEnvironment().getRegion().put(newPut);" . This
will caused an exception when the context's region splite
bq. can call context.complete() to skip other coprocessors.
FYI in hbase-2, complete() has been folded into bypass().
See javadoc of bypass() for details.

In fact, I prevent normal writes, and put the same data with a different
row key(Except row key, they have the same columns and same data).
I have already solved the infinite call by add and check some flag
attribute to Put. If the flag exist then skip my code.
This will prevent the infinite call
Your prePut would write to a different column in the table, right ?
Otherwise do you prevent normal writes from getting into the same column(s)
?
If your prePut writes to dedicated column(s), you can check the presence of
such column(s) so that the call is not infinite.

Yes, It is the same table.

Can you clarify your use case ?
bq. put a data into table
Does your coprocessor write to the same table which receives user data ?

Hello Everyone
I am using the coprocessor and want to put another data when
someone put a data into table. So I try prePut(), but when you call
HRegion.put(), this will call my coprocessor's prePut function again, and
it will cause an dead loop.
My code looks like below, If anyone
