Subject ERROR 2056
Date Thu, 29 Sep 2011 08:42:06 GMT
Hello there,

I'm running pig 0.8 and hadoop-0.18.3.

I'm trying to run some pig job which fails with:
2011-09-29 08:25:31,473 [main] ERROR org.apache.pig.tools.grunt.Grunt -
ERROR 2056: Cannot create exception from empty string.

I've noticed that this problem occurred since I've added another (data) node
to the hadoop cluster.
If I remove that node the problem disappears. I guess that this problem is
rather a hadoop issue than a pig issue. When running hadoop fsck /
it does say that HDFS is healthy... I've also made sure that the newly
created node doesn't contain any garbled data in the hadoop.tmp.dir.

Any ideas what I can do apart from that?
