Ted Yu created HBASE-21138:
------------------------------
Summary: Close HRegion instance at the end of every test in
TestHRegion
Key: HBASE-21138
URL: https://issues.apache.org/jira/browse/HBASE-21138
Project: HBase
Issue Type: Test
Reporter: Ted Yu
TestHRegion has over 100 tests.
The following is from one subtest:
{code}
public void testCompactionAffectedByScanners() throws Exception {
byte[] family = Bytes.toBytes("family");
this.region = initHRegion(tableName, method, CONF, family);
{code}
this.region is not closed at the end of the subtest.
testToShowNPEOnRegionScannerReseek is another example.
Every subtest should use the following construct toward the end:
{code}
} finally {
HBaseTestingUtility.closeRegionAndWAL(this.region);
{code}
