Subject [jira] Commented: (HIVE-457) ScriptOperator should NOT cache all data in stderr
Date Mon, 21 Dec 2009 19:23:18 GMT

    [ https://issues.apache.org/jira/browse/HIVE-457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12793309#action_12793309
] 

Zheng Shao commented on HIVE-457:
---------------------------------

Unfortunately the function readLine(Text, long, long) is not available in hadoop 0.17.

http://hadoop.apache.org/common/docs/r0.17.2/api/org/apache/hadoop/mapred/LineRecordReader.LineReader.html

We can either:
1. Add this to shims;
2. Wait after we branched off hive 0.5.  We might want to drop the support of hadoop 0.17
starting from Hive 0.6.

> Sometimes user scripts output a lot of data to stderr without a new line, and this causes
Hive to go out-of-memory.
> We should directly output the data from stderr without caching it.
