Li Lu commented on YARN-2314: ----------------------------- Hi [~wangda], maybe we want to leave a note in the config, saying that enabling the RPC cache may cause problems for large cluster (so that people would know the possible side-effect of enabling this)? > ContainerManagementProtocolProxy can create thousands of threads for a large > cluster > ------------------------------------------------------------------------------------ > > Key: YARN-2314 > URL: https://issues.apache.org/jira/browse/YARN-2314 > Project: Hadoop YARN > Issue Type: Bug > Components: client > Affects Versions: 2.1.0-beta > Reporter: Jason Lowe > Assignee: Jason Lowe > Priority: Critical > Attachments: disable-cm-proxy-cache.patch, > nmproxycachefix.prototype.patch > > > ContainerManagementProtocolProxy has a cache of NM proxies, and the size of > this cache is configurable. However the cache can grow far beyond the > configured size when running on a large cluster and blow AM address/container > limits. More details in the first comment. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
