> when issuing "alter table " command to rename a kudu table  from impala-shell, impala throw a exception  "operation timeout"
> sql is like "alter table xx rename coupontype_new coupontype int"
> After that , found the column is not renamed , the column is still named "coupontype_new " from impala. but the column has been altered to coupontype on kudu-master ui. with version=1.
>  Meanwhile the table is not readable anymore due to "unknown column" exception.
> Using a java-client (both 0.10.0 and 1.2) to get schema, found the column's name is still the old one : "coupontype_new" .(which is strange, on kudu-master ui' the column's name has been changed to new name "coupontype")
> after altering kudu-table's column  name back to old one  using java kudu-client , the issue is solved temporarily.
> So the problem is that java kudu-client 's "getSchema" api return different schema infos compared with those shown on kudu-master ui.
