----------------------------------------------
Summary: KuduPartitionExpr incorrectly handles its child types
Key: IMPALA-5871
URL: https://issues.apache.org/jira/browse/IMPALA-5871
Project: IMPALA
Issue Type: Bug
Components: Frontend
Affects Versions: Impala 2.10.0
Reporter: Thomas Tauber-Marshall
Priority: Critical
KuduPartitionExpr takes input rows and sends them to Kudu to determine the
partition the rows correspond to in a particular table's partitioning scheme.
If the input types are not the same as (but are compatible with) the types of
the columns in the table, we need to cast the input rows.
KuduPartitionExpr.analyze actually already does this, but the casts may be
dropped in some cases, leading to a crash in the BE.
In particular, attempting to insert a string value into a Kudu timestamp column
fails.
