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-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
