Hi Todd, I'm getting this behavior in another cluster too, there the same thing happens. and as I don't have a jstack installed in the first cluster and I'm not the admin, I'm sending the results of the second cluster.
These are the results: [erl...@cohiba ~ ]$ jstack -l 22510 22510: well-known file is not secure [erl...@cohiba ~ ]$ jstack -l 3836 3836: well-known file is not secure The jstack -F result is in thread_dump files and the jstack -m result is in java_native_frames. The files ending with nn are the namenode results and the files ending with dn are the datanode results.
