-----------------------------------
Summary: Make the list of SerDes supported by REPLACECOLS a
configuration property
Key: HIVE-4890
URL: https://issues.apache.org/jira/browse/HIVE-4890
Project: Hive
Issue Type: New Feature
Affects Versions: 0.10.0
Environment: CDH4.3, Hive 0.10
Reporter: Johndee Burks
Priority: Minor
It would be nice to make the SerDes supported by REPLACECOLS configurable via a
configuration property. For instance you cannot use this REPLACECOLS on a table
with a RegEx SerDe, brought up here
https://issues.apache.org/jira/browse/HIVE-4672.
3062 } else if (alterTbl.getOp() ==
AlterTableDesc.AlterTableTypes.REPLACECOLS) {
3063 // change SerDe to LazySimpleSerDe if it is columnsetSerDe
3064 if (tbl.getSerializationLib().equals(
3065 "org.apache.hadoop.hive.serde.thrift.columnsetSerDe")) {
3066 console
3067 .printInfo("Replacing columns for columnsetSerDe and
changing to LazySimpleSerDe");
3068 tbl.setSerializationLib(LazySimpleSerDe.class.getName());
3069 } else if (!tbl.getSerializationLib().equals(
3070 MetadataTypedColumnsetSerDe.class.getName())
3071 &&
!tbl.getSerializationLib().equals(LazySimpleSerDe.class.getName())
3072 &&
!tbl.getSerializationLib().equals(ColumnarSerDe.class.getName())
3073 &&
!tbl.getSerializationLib().equals(DynamicSerDe.class.getName())) {
3074 formatter.consoleError(console,
3075 "Replace columns is not supported for
this table. "
3076 + "SerDe may be incompatible.",
3077 formatter.ERROR);
