Hi,

This exception generaly means that your GC is using too much CPU time.

Most of the time it means that the JVM size is too small for tha data/treatment to be processed.

And sometimes it's because of a faulty join in the query that generate too many match on the join key.

What kind of query are you using ?
And what is the configuration for the map and reduce JVM size ?
