72 -- getHiveTable()
73 -- DESCRIPTION
74 -- getHiveTable() is a pipelined table function that returns the rows back
75 -- from C external procedures via ODCI to PL/SQL. The rows sent from C
76 -- external procedures actually originate from various Hive metastores and
77 -- fetched via JNI calls made from hotspot JVM
78 --
79 -- PARAMETERS
80 -- configDir - The absolute path of the ORACLE_BIGDATA_CONFIG directory
81 -- *** IMPORTANT *** The first 8 characters of configDir should include the
82 -- length of configDir.
83 -- clusterName - The name of the Hadoop cluster where data is coming from
84 -- dbName - The Hive database name where the data is coming from
85 -- tblName - The Hive table where the data is coming from
86 -- createPartitions - Indicates whether to add Hive partition key columns
87 -- to external table's column list
88 -- callType - one of (0, 1, 2, 3).
89 -- - 0: Will fetch only database related Hive metadata
90 -- - 1: Will fetch only table related Hive metadata
91 -- - 2: Will fetch only column related Hive metadata
92 -- - 3: Will generate a create external table DDL for a
93 -- specified Hive table

95 -- RETURNS
96 -- hiveTypeSet as pipelined rows
