Todd Lipcon commented on HDFS-4182: ----------------------------------- Hi Robert. Nope, I haven't started working on it, so feel free to pick it up. Thanks > SecondaryNameNode leaks NameCache entries > ----------------------------------------- > > Key: HDFS-4182 > URL: https://issues.apache.org/jira/browse/HDFS-4182 > Project: Hadoop HDFS > Issue Type: Bug > Components: name-node > Affects Versions: 0.23.4, 3.0.0, 2.0.2-alpha > Reporter: Todd Lipcon > Priority: Critical > > We recently saw an issue where a 2NN ran out of memory, even though it had a > relatively small fsimage. When we looked at the heap dump, we saw that all of > the memory had gone to entries in the NameCache. > It appears that the NameCache is staying in "initializing" mode forever, and > therefore a long running 2NN leaks entries. -- This message is automatically generated by JIRA.
