Subject [jira] [Commented] (CARBONDATA-1305) On creating the dictinary with large dictionary csv NegativeArraySizeException is thrown
Date Mon, 04 Sep 2017 14:41:00 GMT

    [ https://issues.apache.org/jira/browse/CARBONDATA-1305?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16152672#comment-16152672
] 

Venkata Ramana G commented on CARBONDATA-1305:
----------------------------------------------

Analysis: During dictionary creation the dictionary values are kept in a HashSet. When the
size of hashset reaches more than 500000000 this exception is thrown.

Solution: Limit the dictionary values to 10000000
