Guangming Zhang created YARN-7578:
-------------------------------------
Summary: Extend TestDiskFailures.waitForDiskHealthCheck() sleeping
time.
Key: YARN-7578
URL: https://issues.apache.org/jira/browse/YARN-7578
Project: Hadoop YARN
Issue Type: Test
Affects Versions: 3.1.0
Environment: ARMv8 AArch64, Ubuntu16.04
Reporter: Guangming Zhang
Priority: Minor
Fix For: 3.1.0
Thread.sleep() function is called to wait for NodeManager to identify disk
failures. But in some cases, for example the lower-end hardware computer, the
sleep time is too short so that the NodeManager may haven't finished
identifying disk failures. This will occur test errors:
{code:java}
Running org.apache.hadoop.yarn.server.TestDiskFailures

{code}
So extend the sleep time from 1000ms to 1500ms to avoid some unit test errors.
