Yan Zhou commented on PIG-937:
------------------------------
This bug has been fixed in a patch (see
https://issues.apache.org/jira/browse/PIG-918) pretty much along the same line
as suggested.
> Task get stuck in BasicTable's BTScaner's atEnd() method

> Key: PIG-937
> URL: https://issues.apache.org/jira/browse/PIG-937
> Project: Pig
> Issue Type: Bug
> Reporter: He Yongqiang
>
> It seems is caused by the infinite loop in the code:
> BasicTable, Line 698
> {noformat}
> while (true)
> {
> int index = random.nextInt(cgScanners.length - 1) + 1;
> if (cgScanners[index] != null) {
> if (cgScanners[index].atEnd() != ret) {
> throw new IOException(
> "atEnd() failed: Column Groups are not evenly positioned.");
> }
> break;
> }
> }
> {noformat}
> I think it's fine to just use a for loop here, like:
> {noformat}
> for (int index = 0; index < cgScanners.length; index++) {
> if (cgScanners[index] != null) {
> if (cgScanners[index].atEnd() != ret) {
> throw new IOException(
> "atEnd() failed: Column Groups are not evenly positioned.");
> }
> break;
> }
> }
> {noformat}
