This can cause performance issues if the textual data which > we intend to store is beyond this point. > Instead, let's max out the array to the maximum. Based on different sources, > a safe choice seems to be Integer.MAX_VALUE - 8 (see ArrayList, > AbstractCollection, HashTable, etc). -- 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
