Summary: Intermittent OutOfMemory error while performing hdfs CopyFromLocal to abfs Key: HADOOP-17195 URL: https://issues.apache.org/jira/browse/HADOOP-17195 Project: Hadoop Common Issue Type: Bug Components: fs/azure Affects Versions: 3.3.0 Reporter: Mehakmeet Singh Assignee: Mehakmeet Singh OutOfMemory error due to new ThreadPools being made each time AbfsOutputStream is created. Since threadPool aren't limited a lot of data is loaded in buffer and thus it causes OutOfMemory error. Possible fixes: - Limit the number of ThreadCounts while performing hdfs copyFromLocal (Using -t property). - Reducing OUTPUT_BUFFER_SIZE significantly which would limit the amount of buffer to be loaded in threads. - Don't create new ThreadPools each time AbfsOutputStream is created and limit the number of ThreadPools each AbfsOutputStream could create. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
