--------------------------------
Summary: VolumeScanner prints incorrect IOException in
reportBadBlocks operation
Key: HDFS-10626
URL: https://issues.apache.org/jira/browse/HDFS-10626
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Yiqun Lin
Assignee: Yiqun Lin
VolumeScanner throws incorrect IOException in {{datanode.reportBadBlocks}}. The
related codes:
{code}
public void handle(ExtendedBlock block, IOException e) {
FsVolumeSpi volume = scanner.volume;
...
try {
scanner.datanode.reportBadBlocks(block, volume);
} catch (IOException ie) {
// This is bad, but not bad enough to shut down the scanner.
LOG.warn("Cannot report bad " + block.getBlockId(), e);
}
}
{code}
The IOException that printed in the log should be {{ie}} rather than {{e}}
which was passed in method {{handle(ExtendedBlock block, IOException e)}}.
