----------------------------------------
Summary: Inconsistent log level practices
Key: HDFS-14339
URL: https://issues.apache.org/jira/browse/HDFS-14339
Project: Hadoop HDFS
Issue Type: Improvement
Components: nfs
Affects Versions: 2.8.5, 3.1.0
Reporter: Anuhan Torgonshar
Attachments: RpcProgramNfs3.java
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 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 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.
