Adds erasure coding policy to introspection commands SHOW FILES, SHOW PARTITIONS, SHOW TABLE STATS, and DESCRIBE EXTENDED. Remove `throws IOException` for methods that don't throw. Removes null check for getSd because getStorageDescriptorInfo - which is called right after getTableMetaDataInformation - uses it without checking for null. Adds '$ERASURECODE_POLICY' for runtime test substitution. The test suite replaces this with the current erasure code policy - from HDFS_ERASURECODE_POLICY - or NONE to match expected output. Testing: - ran backend, end-to-end, and custom cluster tests with erasure coding - ran backend, end-to-end, and custom cluster tests with exhaustive strategy Change-Id: Idd95f2d18b3980581788c92993b6d2f53504b5e0 Reviewed-on: http://gerrit.cloudera.org:8080/19268 Reviewed-by: Michael Smith <michael.smith@cloudera.com> Tested-by: Michael Smith <michael.smith@cloudera.com>
