-------------------------------------
Summary: Typos in 7 log messages
Key: HDFS-10862
URL: https://issues.apache.org/jira/browse/HDFS-10862
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Mehran Hassani
Priority: Trivial
I am conducting research on log related bugs. I tried to make a tool to fix
repetitive yet simple patterns of bugs that are related to logs. Typos in log
messages are one of the reoccurring bugs. Therefore, I made a tool find typos
in log statements. During my experiments, I managed to find the following typos
in Hadoop HDFS:
In file
/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/BPServiceActor.java,
LOG.info((success ? "S" : "Uns") +"uccessfully sent block report 0x"
+Long.toHexString(reportId) + " containing " + reports.length +" storage
report(s) of which we sent " + numReportsSent + "." +" The reports had " +
totalBlockCount +" total blocks and used " + numRPCs +" RPC(s). This took " +
brCreateCost +" msec to generate and " + brSendCost +" msecs for RPC and NN
processing." +" Got back " +((nCmds == 0) ? "no commands" :((nCmds == 1) ? "one
command: " + cmds.get(0) :(nCmds + " commands: " + Joiner.on(";
").join(cmds)))) +"."),
uccessfully successfully
In file
/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/DataXceiverServer.java,
LOG.info("Balancing bandwith is " + bandwidth + " bytes/s"),
bandwith should be bandwidth
In file
/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/fsdataset/impl/FsVolumeList.java,
FsDatasetImpl.LOG.info("The volume " + v + " is closed while " +"addng
replicas ignored."),
addng should be adding
In file
/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/CancelDelegationTokenServlet.java,
LOG.info("Exception while cancelling token. Re-throwing. " e),
cancelling should be canceling
In file
/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSDirectory.java,
NameNode.LOG.info("Caching file names occuring more than " + threshold+ "
times"),
occuring should be occurring
In file
/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/NNStorage.java,
LOG.info("NNStorage.attemptRestoreRemovedStorage: check removed(failed)
"+"storarge. removedStorages size = " + removedStorageDirs.size()),
storarge should be storage
In file
/hadoop-hdfs-project/hadoop-hdfs-nfs/src/main/java/org/apache/hadoop/hdfs/nfs/nfs3/RpcProgramNfs3.java,
LOG.info("Partical read. Asked offset: " + offset + " count: " + count+ " and
read back: " + readCount + " file size: "+ attrs.getSize()),
Partical should be Partial
