Pierre N. commented on CASSANDRA-12012:
---------------------------------------
hasSupportingIndex() of
org.apache.cassandra.cql3.restrictions.PrimaryKeyRestrictionSet is doing
Keyspace.openAndGetStore(cfm) which trigger error because of uninitialized
keyspace in client mode.
I hotfixed by adding this check :
{code}
+import org.apache.cassandra.config.Config;
import org.apache.cassandra.cql3.QueryOptions;
import org.apache.cassandra.cql3.functions.Function;
import org.apache.cassandra.cql3.statements.Bound;
@@ -115,7 +116,7 @@ final class PrimaryKeyRestrictionSet extends
AbstractPrimaryKeyRestrictions
this.isPartitionKey = primaryKeyRestrictions.isPartitionKey;
this.cfm = primaryKeyRestrictions.cfm;
- if (!primaryKeyRestrictions.isEmpty() &&
!hasSupportingIndex(restriction))
+ if (!Config.isClientMode() && !primaryKeyRestrictions.isEmpty() &&
!hasSupportingIndex(restriction))
{
ColumnDefinition lastRestrictionStart =
primaryKeyRestrictions.restrictions.lastRestriction().getFirstColumn();
ColumnDefinition newRestrictionStart =
restriction.getFirstColumn();
n))
{code}
It works and generate a valid sstable, however, not sure this is the best way
to fix it.
