Description

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/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/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
