> One of our users has observed below error when our cluster upgrades from 0.98.12 to 1.1.2:
> {noformat}
> java.lang.IllegalArgumentException: Can not create a Path from a null string
> at org.apache.hadoop.fs.Path.checkPathArg(Path.java:122)
> at org.apache.hadoop.fs.Path.<init>(Path.java:134)
> at org.apache.hadoop.fs.Path.<init>(Path.java:88)
> at org.apache.hadoop.hbase.mapreduce.HFileOutputFormat2.configurePartitioner(HFileOutputFormat2.java:639)
> at org.apache.hadoop.hbase.mapreduce.HFileOutputFormat2.configureIncrementalLoad(HFileOutputFormat2.java:489)
> {noformat}
> And checking the application code:
> {code}
> private Job createJob(Configuration jobConf) throws IOException {
> String tableName = jobConf.get(TABLE_NAME_KEY);
> Job job = new Job(jobConf);
> Configuration tableConf = HBaseConfiguration.create();
> HTable table = new HTable(tableConf, tableName);
> HFileOutputFormat2.configureIncrementalLoad(job, table);
> return job;
> }
> {code}
> We could see the user has his own hbase-independent job configuration, so our current code in HFileOutputFormat2:
> {code}
> Path partitionsPath = new Path(conf.get("hbase.fs.tmp.dir"), "partitions_" + UUID.randomUUID());
> {code}
> will return a null string and cause the above exception.
> We propose to add default value in the code rather than depend on hbase-default.xml in this JIRA.
> This is an improvement for HBASE-13625
