-------------------------------
Summary: Apache Spark stucks while reading Kudu table.
Key: KUDU-2210
URL: https://issues.apache.org/jira/browse/KUDU-2210
Project: Kudu
Issue Type: Bug
Components: spark
Reporter: Andrew Ya
When I try reading Kudu table with Apache Spark using following code
{code}
import org.apache.kudu.spark.kudu._
import sqlContext.implicits._
val kuduOptions: Map[String, String] = Map(
"kudu.table" -> "test_table",
"kudu.master" -> "host1:7051,host2:7051,host3:7051")
val kuduDF = sqlContext.read.options(kuduOptions).kudu
kuduDF.registerTempTable("t")
sqlContext.sql(" SELECT * FROM t where id in (1111,2222) ").show(50, false)
{code}
after completing 95% of tasks the job stucks for more than three days. The
table is partitioned by date and partitions have uneven size. Table have one
partition 12 Gb size, about 20 partitions with size between 1 Gb and 3 Gb and
some partitions with Mb's and kb's of data.
