---------------------------------
Summary: Relax FSImage upload time delta check restriction
Key: HDFS-15293
URL: https://issues.apache.org/jira/browse/HDFS-15293
Project: Hadoop HDFS
Issue Type: Improvement
Components: namenode
Reporter: Chen Liang
Assignee: Chen Liang
HDFS-12979 introduced the logic that, if ANN sees consecutive fs image upload
from Standby with a small delta comparing to previous fsImage. ANN would reject
this image. This is to avoid overly frequent fsImage in case of when there are
multiple Standby node. However this check could be too stringent.
