Kihwal Lee created HDFS-5558:
--------------------------------
Summary: LeaseManager monitor thread can crash if the last block
is complete but another block is not.
Key: HDFS-5558
URL: https://issues.apache.org/jira/browse/HDFS-5558
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Kihwal Lee
As mentioned in HDFS-5557, a file has its last and penultimate block not
completed and the file is being closed, the last block can be completed but the
penultimate one might not. If this condition lasts long and the file is
abandoned, LeaseManager will try to recover the lease and the block. But {{
internalReleaseLease}} will fail with invalid cast exception with this kind of
file.
