Using Hadoop's optimized LineRecordReader for reading Tuples in PigStorage ---------------------------------------------------------------------------
Key: PIG-960 URL: https://issues.apache.org/jira/browse/PIG-960 Project: Pig Issue Type: Improvement Components: impl Reporter: Ankit Modi PigStorage's reading of Tuples ( lines ) can be optimized using Hadoop's {{LineRecordReader}}. This can help in following areas - Improving performance reading of Tuples (lines) in {{PigStorage}} - Any future improvements in line reading done in Hadoop's {{LineRecordReader}} is automatically carried over to Pig Issues that are handled by this patch - BZip uses internal buffers and positioning for determining the number of bytes read. Hence buffering done by {{LineRecordReader}} has to be turned off - Current implementation of {{LocalSeekableInputStream}} does not implement {{available}} method. This method has to be implemented. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
