James Clampffer created HDFS-8790: ------------------------------------- Summary: Add Filesystem level stress tests Key: HDFS-8790 URL: https://issues.apache.org/jira/browse/HDFS-8790 Project: Hadoop HDFS Issue Type: Sub-task Components: hdfs-client Reporter: James Clampffer Assignee: James Clampffer
I propose adding stress tests on libhdfs(3) compatibility layer was well as the async calls. These can be also used for basic performance metrics and inputs to profiling tools to see improvements over time. I'd like to make these tests into a seperate executable, or set of them, so that they can be used for longer running tests on dedicated clusters that may already exist. Each should provide a simple command line interface for scripted or manual use. Basic tests would be: looped open-read-close sequential scans small random reads All tests will be parameterized for number of threads, read size, and upper and lower offset bounds for a specified file. This will make it much easier to detect and reproduce threading issues and resource leaks as well as provide a simple executable (or set of executables) that can be run with valgrind to gain a high confidence that the code is operating correctly. I'd appreciate suggestions for any other simple stress tests. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
