Andrey Stepachev commented on HBASE-13574:
------------------------------------------
It seems that test is broken due of the new create retry policy in hadoop 2.6.
Namenode proxy now created with custom RetryPolicy for
AlreadyBeingCreatedException which
is implies timeout on this operations up to
HdfsConstants.LEASE_SOFTLIMIT_PERIOD (60seconds).
So we should expect that create can execute as minimum as this constant if file
already exists.
So for now we can fix that by hardcoding greater timeouts to HBaseFsck (for now
they
are 15 seconds in test and 30seconds in HbaseFsck itself).
This change should not break production usage of HBaseFsck, except of it will
take longer to
find out that other instance of HbaseFsck is running.
