> HIVE-3443 added support to change the serdeParams from 'metatool updateLocation' command.
> However, in avro it is possible to specify the schema via the tableParams:
> {noformat}
> CREATE  TABLE `testavro`(
>   `test` string COMMENT 'from deserializer')
> ROW FORMAT SERDE 
>   'org.apache.hadoop.hive.serde2.avro.AvroSerDe' 
> STORED AS INPUTFORMAT 
>   'org.apache.hadoop.hive.ql.io.avro.AvroContainerInputFormat' 
> OUTPUTFORMAT 
>   'org.apache.hadoop.hive.ql.io.avro.AvroContainerOutputFormat'
> TBLPROPERTIES (
>   'avro.schema.url'='hdfs://namenode:8020/tmp/test.avsc', 
>   'kite.compression.type'='snappy', 
>   'transient_lastDdlTime'='1427996456')
> {noformat}
> Hence for those tables the 'metatool updateLocation' will not help.
> This is necessary in case like upgrade the namenode to HA where the absolute paths have changed.
