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? Thanks, -Marco
