Adam Roberts created SPARK-17524: ------------------------------------ Summary: RowBasedKeyValueBatchSuite always uses 64 mb page size Key: SPARK-17524 URL: https://issues.apache.org/jira/browse/SPARK-17524 Project: Spark Issue Type: Improvement Components: Tests Affects Versions: 2.1.0 Reporter: Adam Roberts Priority: Minor
The appendRowUntilExceedingPageSize test at sql/catalyst/src/test/java/org/apache/spark/sql/catalyst/expressions/RowBasedKeyValueBatchSuite.java always uses the default page size which is 64 MB for running the test Users with less powerful machines (e.g. those with two cores) may opt to choose a smaller spark.buffer.pageSize value in order to prevent problems acquiring memory If this size is reduced, let's say to 1 MB, this test will fail, here is the problem scenario We run with 1,048,576 page size (1 mb) Default is 67,108,864 size (64 mb) Test fails: java.lang.AssertionError: expected:<14563> but was:<932067> 932,067 is 64x bigger than 14,563 and the default page size is 64x bigger than 1 MB (which is when we see the failure) The failure is at Assert.assertEquals(batch.numRows(), numRows); This minor improvement has the test use whatever the user has specified (looks for spark.buffer.pageSize) to prevent this problem from occurring for anyone testing Apache Spark on a box with a reduced page size. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
