Rui Li commented on HDFS-8968: ------------------------------ Hi [~drankye], the tool is intended to test and compare throughput of EC and replication mode. And it does require some EC APIs to run, e.g. {{DFSClient::setErasureCodingPolicy}}. So I didn't give it a general name. Let me know if you think otherwise. > New benchmark throughput tool for striping erasure coding > --------------------------------------------------------- > > Key: HDFS-8968 > URL: https://issues.apache.org/jira/browse/HDFS-8968 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Kai Zheng > Assignee: Rui Li > Attachments: HDFS-8968-HDFS-7285.1.patch, HDFS-8968-HDFS-7285.2.patch > > > We need a new benchmark tool to measure the throughput of client writing and > reading considering cases or factors: > * 3-replica or striping; > * write or read, stateful read or positional read; > * which erasure coder; > * striping cell size; > * concurrent readers/writers using processes or threads. > The tool should be easy to use and better to avoid unnecessary local > environment impact, like local disk. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
