-------------------------------------------
Summary: Improve error messages during table creation
Key: KUDU-1709
URL: https://issues.apache.org/jira/browse/KUDU-1709
Project: Kudu
Issue Type: Bug
Components: impala
Affects Versions: 1.0.1
Reporter: Dimitris Tsirogiannis
Priority: Minor
In some cases the error messages returned from the Java client after a call to
createTable() are not particularly user friendly. For example, running the
following statement from Impala results in the following error:
{code}
impala>create table foo (x int, y int, primary key(y)) distribute by hash (y)
into 3 buckets stored as kudu;
impala>NonRecoverableException: Got out-of-order key column: name: "y" type:
INT32 is_key: true isnullable: false cfile_block_size: 0
{code}
Other cases where the messages could be improved are:
* Setting number of hash buckets to 1: error doesn't indicate which is the
problematic HASH distribute by param
* Using the same column in multiple HASH distribute by params: "hash bucket
schema components must not contain columns in common".
