[jira] [Created] (HDFS-4862) SafeModeInfo.isManual() returns true when resources are low even if it wasn't entered into manually

Ravi Prakash created HDFS-4862:
----------------------------------

             Summary: SafeModeInfo.isManual() returns true when resources are low even if it wasn't entered into manually
                 Key: HDFS-4862
                 URL: https://issues.apache.org/jira/browse/HDFS-4862
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.0.4-alpha, 0.23.7, 3.0.0
            Reporter: Ravi Prakash


HDFS-1594 changed isManual to this
{code}
private boolean isManual() {
  return extension == Integer.MAX_VALUE && !resourcesLow;
}
{code}
One immediate impact of this is that when resources are low, the NN will throw away all block reports from DNs. This is undesirable.
