------------------------------
Summary: TestTableResource fails with NPE
Key: HBASE-21076
URL: https://issues.apache.org/jira/browse/HBASE-21076
Project: HBase
Issue Type: Test
Reporter: Ted Yu
The following can be observed in master branch:
{code}
java.lang.NullPointerException
at
org.apache.hadoop.hbase.rest.TestTableResource.setUpBeforeClass(TestTableResource.java:134)
{code}
The NPE comes from the following in TestEndToEndSplitTransaction :
{code}
compactAndBlockUntilDone(TEST_UTIL.getAdmin(),
TEST_UTIL.getMiniHBaseCluster().getRegionServer(0),
daughterA.getRegionName());
{code}
Initial check of the code shows that TestEndToEndSplitTransaction uses
TEST_UTIL instance which is created within TestEndToEndSplitTransaction.
However, TestTableResource creates its own instance of HBaseTestingUtility.
Meaning TEST_UTIL.getMiniHBaseCluster() would return null, since the instance
created by TestEndToEndSplitTransaction has hbaseCluster as null.
