Zhe Zhang created HDFS-9329:
-------------------------------
Summary: TestBootstrapStandby#testRateThrottling is flaky because
fsimage size is smaller than IO buffer size
Key: HDFS-9329
URL: https://issues.apache.org/jira/browse/HDFS-9329
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Affects Versions: 2.7.1
Reporter: Zhe Zhang
Assignee: Zhe Zhang
Priority: Minor
{{testRateThrottling}} verifies that bootstrap transfer should timeout with a
very small {{DFS_IMAGE_TRANSFER_BOOTSTRAP_STANDBY_RATE_KEY}} value. However,
throttling on the image sender only happens after sending each IO buffer.
Therefore, the test sometimes fails if the receiver receives the full fsimage
(which is smaller than IO buffer size) before throttling begins.
