-----------------------------------------
Since it's [~OneisAll]'s patch, I went ahead and reassigned the JIRA to him.
> Inconsistent log level practices in RpcProgramNfs3.java
> -------------------------------------------------------

> Key: HDFS-14339

> Reporter: Anuhan Torgonshar
> Assignee: Anuhan Torgonshar

> There are *inconsistent* log level practices in
> _*hadoop-2.8.5-src/hadoop-hdfs-project/hadoop-hdfs-nfs/src/main/java/org/apache/hadoop/hdfs/nfs/nfs3/**RpcProgramNfs3.java*_.
>
> {code:java}
> //following log levels are inconsistent with other practices which seems to
> more appropriate
> //from line 1814 to 1819 & line 1831 to 1836 in Hadoop-2.8.5 version
> try {
> attr = writeManager.getFileAttr(dfsClient, childHandle, iug);
> } catch (IOException e) {
> LOG.error("Can't get file attributes for fileId: {}", fileId, e);
> continue;
> }
> //other 2 same practices in this file
> //from line 907 to 911 & line 2102 to 2106
> try {
> postOpAttr = writeManager.getFileAttr(dfsClient, handle, iug);
> } catch (IOException e1) {
> LOG.info("Can't get postOpAttr for fileId: {}", e1);
> }
> //other 3 similar practices
> //from line 1224 to 1227 & line 1139 to 1143 &line 1309 to 1313
> try {
> postOpDirAttr = Nfs3Utils.getFileAttr(dfsClient, dirFileIdPath, iug);
> } catch (IOException e1) {
> LOG.info("Can't get postOpDirAttr for {}", dirFileIdPath, e1);
> }
> {code}
> Therefore, when the code catches _*IOException*_ for _*getFileAttr()*_
> method, it more likely prints a log message with _*INFO*_ level, a lower
> level, a higher level may be scary the users in future.
