[jira] [Commented] (PIG-2926) TestPoissonSampleLoader failing on
rhel environment
[ https://issues.apache.org/jira/browse/PIG-2926?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13460691#comment-13460691 ]
Koji Noguchi commented on PIG-2926:
-----------------------------------
I have no understanding of how this loader works, but the difference is coming at
{noformat}
106 long availRedMem = (long) (Runtime.getRuntime().maxMemory() * heapPerc);
{noformat}
Inside build.xml, test is set up to use -Xmx1024m, however
On my mac, maxMemory() returns 1037959168 whereas on my rhel environemt, it returns 954466304.
Hardcoding this value in the code would make the test pass.
On my macbook.
