Runs fail when tabled cached...

[slavitch]

I'm running spark-sql-perf in a scenario where you would cache tables in RAM for performance reasons. Code here.

The result is blockmanager failing, see the trace below...

val sqlContext = new org.apache.spark.sql.SQLContext(sc)
import sqlContext.implicits._
import com.databricks.spark.sql.perf.tpcds.Tables
import com.databricks.spark.sql.perf.tpcds.TPCDS
val tableNames = Array("call_center", "catalog_page",
"catalog_returns", "catalog_sales", "customer",
"customer_address", "customer_demographics", "date_dim",
"household_demographics", "income_band", "inventory", "item",
"promotion", "reason", "ship_mode", "store",
"store_returns", "store_sales", "time_dim", "warehouse",
"web_page", "web_returns", "web_sales", "web_site")
for(i <- 0 to tableNames.length - 1) { sqlContext.read.parquet("hdfs://sparkc:9000/sqldata" + "/" + tableNames{i}).registerTempTable(tableNames{i})
sqlContext.cacheTable(tableNames{i})
}
val tpcds = new TPCDS (sqlContext = sqlContext)
val experiment = tpcds.runExperiment(tpcds.tpcds1_4Queries, iterations = 1)
experiment.waitForFinish(606010)
