@animenon
Thanks for thr reply! But, I'm still confused.
As per your point, isExternal is proper (both "True" and "TRUE"). But, why
would tableType have different case based on input for EXTERNAL property?
Below is the code that reads EXTERNAL property from ALTER TABLE command and
sets correct tableType.
https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/DDLTask.java#L4092
```
String externalProp = alterTbl.getProps().get("EXTERNAL");
if (externalProp != null) {
if (Boolean.parseBoolean(externalProp) && tbl.getTableType() ==
TableType.MANAGED_TABLE) {
tbl.setTableType(TableType.EXTERNAL_TABLE);
} else if (!Boolean.parseBoolean(externalProp) && tbl.getTableType()
== TableType.EXTERNAL_TABLE) {
tbl.setTableType(TableType.MANAGED_TABLE);
}
}
```
If you notice, we use Boolean.parseBoolean(externalProp) here which ignores
case.
I didn't get how two values of externalProp ("True" and "TRUE") influences
the table type set via setTableType.
Pls point to what I'm missing here.
