[jira] Created: (HADOOP-2419) HADOOP-1965 breaks nutch
HADOOP-1965 breaks nutch
------------------------
Key: HADOOP-2419
URL: https://issues.apache.org/jira/browse/HADOOP-2419
Project: Hadoop
Issue Type: Bug
Reporter: Paul Saab
When running nutch on trunk, nutch is unable to complete a fetch and the following exceptions are raised:
java.io.EOFException
at java.io.DataInputStream.readFully(DataInputStream.java:180)
at org.apache.nutch.protocol.Content.readFields(Content.java:158)
at org.apache.nutch.util.GenericWritableConfigurable.readFields(GenericWritableConfigurable.java:38)

at org.apache.hadoop.mapred.MapTask$MapOutputBuffer.access$100(MapTask.java:248)
at org.apache.hadoop.mapred.MapTask$MapOutputBuffer$1.run(MapTask.java:413)
Exception in thread "SortSpillThread" java.lang.NegativeArraySizeException
at org.apache.hadoop.io.Text.readString(Text.java:388)
at org.apache.nutch.metadata.Metadata.readFields(Metadata.java:243)

at org.apache.hadoop.mapred.MapTask$MapOutputBuffer$1.run(MapTask.java:413)
After reverting HADOOP-1965 nutch works just fine.

Nigel Daley commented on HADOOP-2419:
-------------------------------------
Amar, does HADOOP-2419.patch cover the same case as MapRunnableTest.java attached to this Jira? If not, it would be good to incorporate the case covered by MapRunnableTest.java.

------------------------------------
Plz check the new patch [https://issues.apache.org/jira/secure/attachment/12371775/HADOOP-2419.patch]. Earlier the calls to {{MapTask.Collect()}} were not thread-safe. Now the call to {{Collect()}} is made thread-safe. Let us know if this patch works fine.

Amar Kamat commented on HADOOP-2419:
------------------------------------
The guess is that {{MapRunnableTest.java{}} assumes that {{MapTask.collect()}} is thread-safe. Which the earlier patch did not provide. So the change makes the call thread-safe.

[jira] Updated: (HADOOP-2419) HADOOP-1965 breaks nutch
Posted by "Paul Saab (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HADOOP-2419?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Paul Saab updated HADOOP-2419:
------------------------------
Attachment: MapRunnableTest.java
This is a sample MR job that mimics what nutch's Fetcher2 does with threads and queuing url's to be fetched. It takes 2 arguments on the command line, an input path and an output path. All it does it reads a TextInputFormat, queues it up for threads to then write it back out as it came in. The sample run I just did came back with the following exception. Reverting HADOOP-1965 allows the job to finish without error.

[jira] Resolved: (HADOOP-2419) HADOOP-1965 breaks nutch
Posted by "Amar Kamat (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HADOOP-2419?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Amar Kamat resolved HADOOP-2419.
--------------------------------
Resolution: Fixed
Assuming that concurrent access to {{MapTask.collect()}} was the cause (which is now fixed in HADOOP-1965), resolving the issue.

Plz check the new patch [https://issues.apache.org/jira/secure/attachment/12371797/HADOOP-2419.patch]. Earlier the calls to {{MapTask.Collect()}} were not thread-safe. Now the call to {{Collect()}} is made thread-safe. Let us know if this patch works fine.
