Subject HBase 0.98 CDH 5.2, significant Read degradation
Date Fri, 13 Mar 2015 09:44:05 GMT
Hi, finally I met HBase perfomance problems :(
I see this message:

Slow sync cost: 345 ms, current pipeline: []

in log file
sometimes [] contains actual addresses of my datanodes.
What are the steps to undestand why HBase is so slow.
I have 7RS and 3K reads per second and 500 writes per second. Requests are
evenly distributed across cluster since I use hash for keys.
