Summary: Correct the safemode threshold value in
BlockManagerSafeMode
Key: HDFS-14719
URL: https://issues.apache.org/jira/browse/HDFS-14719
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 3.1.1
Reporter: Surendra Singh Lilhore
BlockManagerSafeMode is doing wrong parsing for safemode threshold. It is
storing float value in double, which will give different result some time. If
we store "0.999f" value in double then it will be converted to
"0.9990000128746033".
{code:java}
this.threshold = conf.getFloat(DFS_NAMENODE_SAFEMODE_THRESHOLD_PCT_KEY,
DFS_NAMENODE_SAFEMODE_THRESHOLD_PCT_DEFAULT);{code}
