Hi, While trying to execute a query via TableEnvironment.sqlQuery in Flink 1.12, I receive the following exception:
java.lang.NullPointerException <init>:114, RelMetadataQuery (org.apache.calcite.rel.metadata) <clinit>:76, RelMetadataQuery (org.apache.calcite.rel.metadata) get:39, FlinkRelOptClusterFactory$$anon$1 (org.apache.flink.table.planner.calcite) get:38, FlinkRelOptClusterFactory$$anon$1 (org.apache.flink.table.planner.calcite) getMetadataQuery:178, RelOptCluster (org.apache.calcite.plan) create:108, LogicalFilter (org.apache.calcite.rel.logical) createFilter:344, RelFactories$FilterFactoryImpl (org.apache.calcite.rel.core) convertWhere:1042, SqlToRelConverter (org.apache.calcite.sql2rel) convertSelectImpl:666, SqlToRelConverter (org.apache.calcite.sql2rel) convertSelect:644, SqlToRelConverter (org.apache.calcite.sql2rel) convertQueryRecursive:3438, SqlToRelConverter (org.apache.calcite.sql2rel) convertQuery:570, SqlToRelConverter (org.apache.calcite.sql2rel) org$apache$flink$table$planner$calcite$FlinkPlannerImpl$$rel:165, FlinkPlannerImpl (org.apache.flink.table.planner.calcite) rel:157, FlinkPlannerImpl (org.apache.flink.table.planner.calcite) toQueryOperation:823, SqlToOperationConverter (org.apache.flink.table.planner.operations) convertSqlQuery:795, SqlToOperationConverter (org.apache.flink.table.planner.operations) convert:250, SqlToOperationConverter (org.apache.flink.table.planner.operations) parse:78, ParserImpl (org.apache.flink.table.planner.delegation) sqlQuery:639, TableEnvironmentImpl (org.apache.flink.table.api.internal) $anonfun$translateTemplate$2:476, Foo$ (Foo) apply:-1, 644680650 (ai.hunters.pipeline.Processors$$$Lambda$1597) evaluateNow:361, FiberContext (zio.internal) $anonfun$evaluateLater$1:778, FiberContext (zio.internal) run:-1, 289594359 (zio.internal.FiberContext$$Lambda$617) runWorker:1149, ThreadPoolExecutor (java.util.concurrent) run:624, ThreadPoolExecutor$Worker (java.util.concurrent) run:748, Thread (java.lang) This seems to be coming from the FlinkRelMetadataQuery class attempting to initialize all handlers: [image: image.png] This seems to be coming from the calcite shaded JAR inside "flink-table-planner-blink-1.12" Has anyone ran into this issue? I saw a thread in the chinese user group but I don't understand what's been said there ( https://www.mail-archive.com/user-zh@flink.apache.org/msg05874.html) -- Best Regards, Yuval Itzchakov.
