Nandakumar created HDFS-12050: --------------------------------- Summary: Ozone: StorageHandler: Implementation of "close" for releasing resources during shutdown Key: HDFS-12050 URL: https://issues.apache.org/jira/browse/HDFS-12050 Project: Hadoop HDFS Issue Type: Sub-task Components: ozone Reporter: Nandakumar Assignee: Nandakumar
When we use DistributedStorageHandler and call {{newKeyWriter}}, it will create {{XceiverClientSpi}} and add it to clientCache which will create a non-daemon {{nioEventLoopGroup}} thread. Since {{XceiverClientManager#releaseClient}} doesn't invalidate the client, close is not called on the client object. Cleanup is triggered as part of both eviction as well as releaseClient, but the connection is closed only when both of the conditions are satisfied. This {{StorageHandler#close}} can be used close the connections during shutdown. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
