------------------------------------
Summary: Nested retry loops in HConnectionManager
Key: HBASE-6326
URL: https://issues.apache.org/jira/browse/HBASE-6326
Project: HBase
Issue Type: Bug
Reporter: Lars Hofhansl
While testing client timeouts when the HBase is not available we found that
even with aggressive settings, it takes the client 10 minutes or more to
finally receive an exception.
Part of this is due to nested nested retry loops in locateRegion.
locateRegion will first try to locate the table in meta (which is retried),
then it will try to locate the meta table is root (which is also retried).
So for each retry of the meta lookup we retry the root lookup as well.
I have have that avoids locateRegion retrying if it is called from code that
already has a retry loop.
