[GitHub] [hbase-connectors] LB-Yu opened a new pull request #63: Solve the
ambiguous reference for scala 2.12
LB-Yu opened a new pull request #63: Solve the ambiguous reference for scala 2.12
URL: https://github.com/apache/hbase-connectors/pull/63
When the `hbase-spark` module is compiled under the scala 2.12 environment, the following error appears in line 216 of the `org.apache.hadoop.hbase.spark.datasources.HBaseTableScanRDD` class:
```shell
[ERROR] [Error] /path/hbase-connectors/spark/hbase-spark/src/main/scala/org/apache/hadoop/hbase/spark/datasources/HBaseTableScanRDD.scala:216: ambiguous reference to overloaded definition,
both method addTaskCompletionListener in class TaskContext of type [U](f: org.apache.spark.TaskContext => U)org.apache.spark.TaskContext
and method addTaskCompletionListener in class TaskContext of type (listener: org.apache.spark.util.TaskCompletionListener)org.apache.spark.TaskContext
match argument types (org.apache.spark.TaskContext => Unit)
```
I solve this bug by changing the origin line:
```scala
context.addTaskCompletionListener(context => close())
```
To:
```scala
context.addTaskCompletionListener[Unit](context => close())
```

I ran the command `mvn -Dspark.version=2.4.5 -Dscala.version=2.12.8 -Dscala.binary.version=2.12 clean package` and PASSED all the tests on branch `scala_2.12`.
