+ * Simple example to run a compaction job for MOR table.
+ * To run this example, you should:
+ * 1. For running in IDE, set VM options `-Dspark.master=local[2]`

+ *
+ * Usage: HoodieMorCompactionJob <tablePath> <tableName>.
+ * <tablePath> and <tableName> describe root path of hudi and table name
+ * for example, `HoodieMorCompactionJob file:///tmp/hoodie/hudi_mor_table
hudi_mor_table`

Review comment:
Added try-catch-finally. Looks like try-with-resources is not readily
available in scala versions earlier than 2.13
