Viraj Jasani updated PHOENIX-7700:
----------------------------------
Description:
As part of any ALTER TABLE DDL statement execution, two configs determine the
retry policy while awaiting response from HBase modifyTable operation:
* phoenix.schema.change.retries
* phoenix.schema.change.delay
The default values for "phoenix.schema.change.delay" is 5 sec and for
"phoenix.schema.change.retries" is 10. In majority cases, HBase procedures take
less than a second to complete, therefore awaiting for 5 sec is not helpful.
We should change the default values of delay to 1 sec and retries to 50 to keep
default overall 50sec of wait time before throwing TimeoutException.
Thanks for finding the bug [~dmanning]!
