Hi HBaser, We meet aproblem when we use HBase. Our environment is HBase 0.20.6 + Hadoop (CDH3b2). 5 region server and 5 datanode with 2193 region and 48.95 TB data in HDFS. And our client is put 5 column family and 5 qualifier in one row, and commit to HBase every 500 rows. We start 8 clients in one machine (have 6 machines, totally we have 48 clients) When batch put , we found cost of loadFileInfo became more and more after spliting region , from several ms to tens of seconds, even several minutes. At last, it'll cause error like below.
*org.apache.hadoop.hbase.client.NoServerForRegionException: No server address listed in .META. for region * BTW: After profiling, we found performance waste in readIndex. (mainly in a loop sequencly read byte array from HDFS. ) As putting, readIndex become more slowly. Has any body meet similar issue ?? And help me to explain why read HDFS become slowly. Thanks & Best regards LiuJinglong
