Hi HBasistas, We're experiencing the following behavior when starting our cluster with version 0.90.4-cdh3u2:
Whenever a RS is assigned a large (> 500-600) number of regions, the heap usage grows without bound. Then the RS constantly GCs and must be killed. This is with 2000 regions over 3 RSs, with 10 GB heap. RSs have EC2 xlarges. Master is on its own large. Datanodes and namenodes are adjacent to RSs and master, respectively. Looks like a memory leak? Any suggestions would be appreciated. Thanks, Homer
