Zhihong Yu commented on HBASE-5191:
-----------------------------------
After fixing the compilation error, the test failed with:
{code}
testLogRollOnDatanodeDeath(org.apache.hadoop.hbase.regionserver.wal.TestLogRolling)
Time elapsed: 20.471 sec <<< FAILURE!
java.lang.AssertionError: Need HDFS-826 for this test
at org.junit.Assert.fail(Assert.java:93)
at org.junit.Assert.assertTrue(Assert.java:43)
at
org.apache.hadoop.hbase.regionserver.wal.TestLogRolling.testLogRollOnDatanodeDeath(TestLogRolling.java:318)
{code}
This is the related line:
{code}
assertTrue("Need HDFS-826 for this test", log.canGetCurReplicas());
{code}
This is how we retrieve getNumCurrentReplicas method in HLog:
{code}
private Method getGetNumCurrentReplicas(final FSDataOutputStream os) {
Method m = null;
Exception exception = null;
if (os != null) {
try {
m = os.getWrappedStream().getClass().
getMethod("getNumCurrentReplicas", new Class<?> []{});
m.setAccessible(true);
{code}
Here is the exception:
{code}
java.lang.NoSuchMethodException:
org.apache.hadoop.hdfs.DFSOutputStream.getNumCurrentReplicas()
at java.lang.Class.getMethod(Class.java:1605)
at
org.apache.hadoop.hbase.regionserver.wal.HLog.getGetNumCurrentReplicas(HLog.java:458)
at org.apache.hadoop.hbase.regionserver.wal.HLog.<init>(HLog.java:441)
{code}
