> 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
