Pavel Yaskevich commented on CASSANDRA-2256: -------------------------------------------- Test for the problem: {code} public void testAssertOnRead() throws IOException { BufferedRandomAccessFile file = createTempFile("braf"); file.write(new byte[10]); file.sync(); BufferedRandomAccessFile copy = new BufferedRandomAccessFile(file.getPath(), "r"); copy.seek(15); copy.read(); file.close(); copy.close(); } {code} This happens when you are trying to seek to position > file length on read-only file and then read (because fileLength is cached, method isEOF() does not work properly). I don't think that we should allow such seeks. > BRAF assertion error > -------------------- > > Key: CASSANDRA-2256 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2256 > Project: Cassandra > Issue Type: Bug > Components: Core > Affects Versions: 0.7.3 > Reporter: Jonathan Ellis > Assignee: Pavel Yaskevich > Fix For: 0.7.4 > > > While investigating CASSANDRA-2240 I ran into this: > {noformat} > java.lang.AssertionError > at > org.apache.cassandra.io.util.BufferedRandomAccessFile.read(BufferedRandomAccessFile.java\ > :230) > at java.io.RandomAccessFile.readByte(RandomAccessFile.java:589) > at > org.apache.cassandra.utils.ByteBufferUtil.readShortLength(ByteBufferUtil.java:273) > at > org.apache.cassandra.utils.ByteBufferUtil.readWithShortLength(ByteBufferUtil.java:284) > at > org.apache.cassandra.db.CompactionManager.doScrub(CompactionManager.java:539) > {noformat} -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
