[CARBONDATA-247] Higher MAXCOLUMNS value in load DML options is leading to out of memory error Problem: Higher MAXCOLUMNS value in load DML options is leading to out of memory error Analysis: When a higher value lets say Integer max value is configured for maxcolumns option in load DML and executor memory is less, then in that case UnivocityCsvParser throws an out of memory error when it tries to create an array of size of maxColumns option value. Fix: Set the threshold value for maxColumns option value that our system can support and if maxColumns option value is greater than threshold value then assign the threshold value to maxColumns option value Impact: Data loading You can merge this pull request into a Git repository by running: $ git pull https://github.com/dhatchayani/incubator-carbondata maxColumns_issue Alternatively you can review and apply these changes as the patch at: https://github.com/apache/incubator-carbondata/pull/162.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #162 ---- commit 25ece8bf8cf214324cc2abf2e27bbbb43a16d4a7 Author: manishgupta88 <tomanishgupt...@gmail.com> Date: 2016-09-17T05:22:27Z Problem: Higher MAXCOLUMNS value in load DML options is leading to out of memory error Analysis: When a higher value lets say Integer max value is configured for maxcolumns option in load DML and executor memory is less, then in that case UnivocityCsvParser throws an out of memory error when it tries to create an array of size of maxColumns option value.
