Ming Ma created YARN-3934: ----------------------------- Summary: Application with large ApplicationSubmissionContext can cause RM to exit when ZK store is used Key: YARN-3934 URL: https://issues.apache.org/jira/browse/YARN-3934 Project: Hadoop YARN Issue Type: Bug Reporter: Ming Ma
Use the following steps to test. 1. Set up ZK as the RM HA store. 2. Submit a job that refers to lots of distributed cache files with long HDFS path, which will cause the app state size to exceed ZK's max object size limit. 3. RM can't write to ZK and exit with the following exception. {noformat} 2015-07-10 22:21:13,002 FATAL org.apache.hadoop.yarn.server.resourcemanager.ResourceManager: Received a org.apache.hadoop.yarn.server.resourcemanager.RMFatalEvent of type STATE_STORE_OP_FAILED.
