Tony Wu commented on HDFS-9490:
-------------------------------
The failed tests are not related to this patch. Only
{{TestPendingCorruptDnMessages}} and {{TestNameNodeMetadataConsistency}} uses
the updated {{MiniDFSCluster#changeGenStampOfBlock}}. Both of these tests pass
fine.
Manually ran the failed tests with jdk 1.8 on OSX and they all pass.
The failed JDK 1.7 tests both suffer from permission denied error (might be a
test system issue):
org.apache.hadoop.hdfs.server.namenode.ha.TestRetryCacheWithHA.testListCacheDirectives:
{{Error while running command to get file permissions : ExitCodeException
exitCode=127: /bin/ls: error while loading shared libraries: libc.so.6: failed
to map segment from shared object: Permission denied}}
org.apache.hadoop.hdfs.server.namenode.ha.TestRetryCacheWithHA.testListCacheDirectives:
{{bash: error while loading shared libraries: libdl.so.2: failed to map segment
from shared object: Permission denied}}
The failed JDK 1.8 tests :
TestSeveralNameNodes is tracked by HDFS-9376

> {{MiniDFSCluster#changeGenStampOfBlock}} directly manipulates the block meta
> file to update the generation stamp. This depends on file based {{FsDataset}}.
> We can abstract the change generation stamp operation in
> {{FsDatasetTestUtils}}.
