--------------------------------
Summary: Make TestLazyPersistFiles#testLazyPersistBlocksAreSaved
deterministic
Key: HDFS-7475
URL: https://issues.apache.org/jira/browse/HDFS-7475
Project: Hadoop HDFS
Issue Type: Test
Components: test
Affects Versions: 2.6.0
Reporter: Xiaoyu Yao
Assignee: Xiaoyu Yao
TestLazyPersistFiles#testLazyPersistBlocksAreSaved verifies that the memory
block is saved in lazy persist directory after some sleep with the following
code.
{code}
// Sleep for a short time to allow the lazy writer thread to do its job
Thread.sleep(6 * LAZY_WRITER_INTERVAL_SEC * 1000);
{code}
However, the sleep only guarantees an async lazy persist task is scheduled. The
task running on a per volume thread pool thread can take longer to finish
persisting. It will be more deterministic to wait the pending lazy persist task
count reduce to 0 before verifying the block file exist in lazy persist dir.
