weizheng commented on HIVE-20929:
---------------------------------
If the parameter validTxnList is not passed，the default value is null.
The following is the implementation of
*{color:#FF0000}HiveMetaStoreClient.getValidWriteIds(String
fullTableName).{color}*
public ValidWriteIdList getValidWriteIds(String fullTableName) throws
TException {
GetValidWriteIdsRequest rqst = new
GetValidWriteIdsRequest(Collections.singletonList(fullTableName),
*{color:#FF0000}null{color}*);
GetValidWriteIdsResponse validWriteIds = client.get_valid_write_ids(rqst);
return
TxnUtils.createValidReaderWriteIdList(validWriteIds.getTblValidWriteIds().get(0));
}
so I got errors that {color:#FF0000}Required field 'validTxnList' is
unset!{color}
> The method HiveMetaStoreClient.getValidWriteIds(String fullTableName) failed
> to execute.

> So I can only use the following methods instead：

> tablesList.add(AcidUtils.getFullTableName(table.getDbName(),
> table.getTableName()));
> List<TableValidWriteIds> writeIdList =
> metaStoreClient.getValidWriteIds(tablesList,txns.toString());
> writeIds = TxnUtils.createValidReaderWriteIdList(writeIdList.get(0));
