In most of the cases > there are issues with the Namenode so we have metrics to know the workload or > stress on Namenode. > However, there is a need to have more statistics collected for different > operations/RPCs in DFSClient to know which RPC operations are taking longer > time or to know what is the frequency of the operation.These statistics can > be exposed to the users of DFS Client and they can periodically log or do > some sort of flow control if the response is slow. This will also help to > isolate HDFS issue in a mixed environment where on a node say we have Spark, > HBase and Impala running together. We can check the throughput of different > operation across client and isolate the problem caused because of noisy > neighbor or network congestion or shared JVM. > We have dealt with several problems from the field for which there is no > conclusive evidence as to what caused the problem. If we had metrics or stats > in DFSClient we would be better equipped to solve such complex problems. > List of jiras for reference: > ------------------------- > HADOOP-15538 HADOOP-15530 ( client side deadlock) -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
