Yang Yun created HDFS-14993:
-------------------------------
Summary: checkDiskError doesn't work during datanode startup
Key: HDFS-14993
URL: https://issues.apache.org/jira/browse/HDFS-14993
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode
Reporter: Yang Yun
the function checkDiskError() is called before addBlockPool, but list bpSlices
is empty this time. So the function check() in FsVolumeImpl.java does nothing.
@Override
public VolumeCheckResult check(VolumeCheckContext ignored)
throws DiskErrorException {
// TODO:FEDERATION valid synchronization
for (BlockPoolSlice s : bpSlices.values()) {
s.checkDirs();
}
return VolumeCheckResult.HEALTHY;
}
