experienced something similar. I'm stuck with this and would appreciate any

Many thanks,
Martin

below). Tried to find in this mailing list for the exact problem but was not
successful. These are the symptoms:

Thanks everyone, we're currently testing with 10K and no issues so far.

Hi,
I'm doing an experiment on an 8 node cluster, each of which has 6GB of RAM
allocated to hbase region server. Basically, doing a bulk import processing
