 Key: PIG-960
 URL: https://issues.apache.org/jira/browse/PIG-960
 Project: Pig
  Issue Type: Improvement
  Components: impl
Reporter: Ankit Modi
 Fix For: 0.6.0

 Attachments: pig_rlr.patch


 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.
