This directory is used by the RegionServers durring compactions to store
intermediate data. See:
$ git grep 'hbase.tmp.dir'
hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/CompactionTool.java:
private final static String CONF_TMP_DIR = "hbase.tmp.dir";
hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java:
final Path logdir = new Path(c.get("hbase.tmp.dir"));
...
Both of these uses indicate that it is a single path. I imagine you'd get
exceptions if you attempted to feed it a comma-delimited list of paths.
