> When hudson runs for HBASE-6459, it encounters a failed testcase in org.apache.hadoop.hbase.coprocessor.TestClassLoading.testClassLoadingFromLibDirInJar.
The link is https://builds.apache.org/job/PreCommit-HBASE-Build/2455/testReport/org.apache.hadoop.hbase.coprocessor/TestClassLoading/testClassLoadingFromLibDirInJar/
> I check the log, and find that the function waitTableAvailable will only check the meta
table, when rs open the region and update the metalocation in meta, it may not be added to
the onlineregions in rs.
> for (HRegion region:
>         hbase.getRegionServer(0).getOnlineRegionsLocalContext()) {
> this Loop will ship, and found1 will be false altogether.
> that's why the testcase failed.
> So maybe we can  hbave some strictly check when table is created
