> Improve error reporting for JDBC clients
> ----------------------------------------
>
> Key: IMPALA-3351
> URL: https://issues.apache.org/jira/browse/IMPALA-3351
> Project: IMPALA
> Issue Type: Improvement
> Components: Clients
> Affects Versions: Impala 2.0
> Reporter: Xiaomin Zhang
> Priority: Minor
> Labels: jdbc
>
> For JDBC client such as beeline:
> beeline> !connect jdbc:hive2://quickstart.cloudera:21050/;principal=impala/quickstart.cloudera@CLOUDERA
> For queries such as "SELECT * FROM CUSTOMER", when CUSTOMER does not exist, I get below error:
> Error: AnalysisException: Could not resolve table reference: 'customer' (state=HY000,code=0)
> However, for queries such as "SELECT * FROM CUSTOMERS", when this table is using non-supported definition, I will get below error message:
> Error: Invalid query handle (state=HY000,code=0)
> There's no detailed and useful information returned. The only way to troubleshooting this query is to look into the impalad log, I can see errors like:
> Error from query ca4ae093852af48b:a7d9cec9fae3ab4: File hdfs://quickstart.cloudera:8020/user/hive/warehouse/customers/customers has invalid file metadata at file offset 2183. Error = couldn't deserialize thrift msg:
> TProtocolException: Invalid data
> So this looks that JDBC client cannot get detailed SQL exception when the underlining error happens on fragments.
> Is it possible to also bring those runtime error information to JDBC clients?
