Ted Yu commented on HBASE-9754:
-------------------------------
For 0.94, there were a few test failures which mostly passed on rerun.
The following failure was mysterious:
{code}
testDeleteEditUnknownColumnFamilyAndOrTable(org.apache.hadoop.hbase.client.TestAdmin)
Time elapsed: 2.022 sec <<< FAILURE!
java.lang.AssertionError
at org.junit.Assert.fail(Assert.java:92)
at org.junit.Assert.assertTrue(Assert.java:43)
at org.junit.Assert.assertTrue(Assert.java:54)
at
org.apache.hadoop.hbase.client.TestAdmin.testDeleteEditUnknownColumnFamilyAndOrTable(TestAdmin.java:217)
{code}
It happened with or without patch.
I ran the test suite on Linux.

> Brought up by [~vrodionov] and [[email protected]].
> Currently we use ThreadLocals to communicate the current readpoint between a
> RegionScanner and the Store\{File}Scanner's down the stack.
> Since ThreadLocals are not cheap we should consider whether it is possible to
> pass the readpoint through the call stack instead.
