Hi, finally I met HBase perfomance problems :( I see this message: org.apache.hadoop.hbase.regionserver.wal.FSHLog
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.
