-----------------------------------------
Summary: LobAvroImportTestCase is sensitive to test method order
execution
Key: SQOOP-1185
URL: https://issues.apache.org/jira/browse/SQOOP-1185
Project: Sqoop
Issue Type: Bug
Affects Versions: 1.4.4
Reporter: Jarek Jarcec Cecho
Assignee: Jarek Jarcec Cecho
Fix For: 1.4.5
The test case {{LobAvroImportTestCase}} is sensitive to order in which the
testing methods are executed. When playing with combination of JDK6 and JDK7 I
was able to make it consistently fail. Considering working test case output:
{code}
Testcase: testBlobAvroImportInline took 6.743 sec
Testcase: testBlobAvroImportExternal took 2.364 sec
Testcase: testBlobCompressedAvroImportInline took 2.134 sec
Testcase: testBlobCompressedAvroImportExternal took 1.955 sec
Testcase: testBlobAvroImportMultiCols took 2.836 sec
Testcase: testClobAvroImportInline took 0.065 sec
Testcase: testClobAvroImportExternal took 0.069 sec
Testcase: testClobCompressedAvroImportInline took 0.059 sec
Testcase: testClobCompressedAvroImportExternal took 0.068 sec
Testcase: testClobAvroImportMultiCols took 0.061 sec
{code}
With failing one:
{code}
Testcase: testBlobCompressedAvroImportExternal took 4.106 sec
Testcase: testClobAvroImportMultiCols took 0.069 sec
Testcase: testBlobAvroImportExternal took 1.563 sec
FAILED
null
junit.framework.AssertionFailedError
at
com.cloudera.sqoop.testutil.LobAvroImportTestCase.testBlobAvroImportExternal(LobAvroImportTestCase.java:208)
Testcase: testClobCompressedAvroImportExternal took 0.061 sec
Testcase: testBlobCompressedAvroImportInline took 1.86 sec
Testcase: testClobCompressedAvroImportInline took 0.071 sec
Testcase: testClobAvroImportInline took 0.068 sec
Testcase: testBlobAvroImportInline took 1.584 sec
Testcase: testClobAvroImportExternal took 0.063 sec
Testcase: testBlobAvroImportMultiCols took 1.921 sec
{code}
The test method order is different which seems to be causing the issues. The
failure is on line
[208|https://github.com/apache/sqoop/blob/trunk/src/test/com/cloudera/sqoop/testutil/LobAvroImportTestCase.java#L208]
where we are expecting end of the lob pointer to contain the
[getTableNum()|https://github.com/apache/sqoop/blob/trunk/src/test/com/cloudera/sqoop/testutil/LobAvroImportTestCase.java#L204].
However as the pointer generation is not tied to the table name, but only to a
mapreduce job id, it will work only if the test cases will be executed in
particular order (e.g. getTableNum() and number of executed mapreduce jobs will
be equal).
