-----------------------------------
Summary: Misleading error messages in FSImage.java
Key: HDFS-7757
URL: https://issues.apache.org/jira/browse/HDFS-7757
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.6.0
Reporter: Arpit Agarwal
If a quota violation is detected while loading an image, the NameNode logs
scary error messages indicating a bug. However the quota violation state is
very easy to get into e.g.
# Copy a 2MB file to a directory.
# Set a disk space quota of 1MB on the directory. We are in quota violation
state now.
We should reword the error messages, ideally making them warnings and
suggesting the administrator needs to fix the quotas:
Relevant code:
{code}
LOG.error("BUG: Diskspace quota violation in image for "
+ dir.getFullPathName()
+ " quota = " + dsQuota + " < consumed = " + diskspace);
...
LOG.error("BUG Disk quota by storage type violation in image for "
+ dir.getFullPathName()
+ " type = " + t.toString() + " quota = "
+ typeQuota + " < consumed " + typeSpace);
{code}
