Lars Hofhansl commented on HBASE-7499:
--------------------------------------
I can either increase the scanner timeout slightly (from 10s to maybe 15s - not
too much because another waits for the TO to pass), or the test can make sure
that the table's first region is not located on the same RS that also hosts
.META. Looking at TestSplitTransactionOnCluster it seem the latter approach can
have its own set of problems.
> TestScannerTimeout timeout is too aggressive.
