Zheng Shao updated HADOOP-3144:
-------------------------------
Assignee: Zheng Shao
Release Note: Added a new configuration variable:
mapred.linerecordreader.maxlength (default: Long.MAX_VALUE) to specify the
length of the longest lines. All lines longer than this will be thrown away.
Default behavior does not change.
Status: Patch Available (was: Open)
This patch also makes sure that the LineReader does not read too far into the
next split when it's not necessary.
> better fault tolerance for corrupted text files

> every once in a while - we encounter corrupted text files (corrupted at
> source prior to copying into hadoop). inevitably - some of the data looks
> like a really really long line and hadoop trips over trying to stuff it into
> an in memory object and gets outofmem error. Code looks same way in trunk as
> well ..
> so looking for an option to the textinputformat (and like) to ignore long
> lines. ideally - we would just skip errant lines above a certain size limit.
