Summary: NPE in CalciteSchema during preparation of planning phase
Key: CALCITE-821
URL: https://issues.apache.org/jira/browse/CALCITE-821
Project: Calcite
Issue Type: Bug
Components: core
Reporter: Jesus Camacho Rodriguez
Assignee: Julian Hyde
During testing of 1.4-SNAPSHOT on Hive, we hit the Exception with the following
stacktrace in all our tests:
{noformat}
java.lang.NullPointerException

The problem is that the FrameworkConfig defaultSchema is null. Thus, a NPE is
thrown after hitting this piece of code in Frameworks:
{code}
final CalciteSchema schema =
CalciteSchema.from(config.getDefaultSchema());
{code}
The apply method was changed in CALCITE-748.
