-----------------------------------
Summary: NameNode hangs during startup trying to apply
OP_ADD_PATH_BASED_CACHE_DIRECTIVE.
Key: HDFS-5313
URL: https://issues.apache.org/jira/browse/HDFS-5313
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: HDFS-4949
Reporter: Chris Nauroth
During namenode startup, if the edits contain a
{{OP_ADD_PATH_BASED_CACHE_DIRECTIVE}} for an existing file, then the process
hangs while trying to apply the op. This is because of a call to
{{FSDirectory#setCacheReplication}}, which calls {{FSDirectory#waitForReady}},
but of course nothing is ever going to mark the directory ready, because it's
still in the process of loading.
