WARN - [NIOServerFactory:NIOServerFactory@123] - Exception in server socket loop: /0.0.0.0
java.util.NoSuchElementException
at java.util.HashMap$HashIterator.nextEntry(HashMap.java:796)
at java.util.HashMap$EntryIterator.next(HashMap.java:834)
at java.util.HashMap$EntryIterator.next(HashMap.java:832)
at org.apache.bookkeeper.bookie.LedgerCache.grabCleanPage(LedgerCache.java:429)
at org.apache.bookkeeper.bookie.LedgerCache.putEntryOffset(LedgerCache.java:133)
at org.apache.bookkeeper.bookie.LedgerDescriptor.addEntry(LedgerDescriptor.java:84)
at org.apache.bookkeeper.bookie.Bookie.addEntry(Bookie.java:477)

[jira] [Updated] (BOOKKEEPER-22) Exception in LedgerCache causes
addEntry request to fail
Posted by "Flavio Junqueira (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/BOOKKEEPER-22?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Flavio Junqueira updated BOOKKEEPER-22:
---------------------------------------
Attachment: BOOKKEEPER-22.patch
Includes a test, which fails if we remove the fix in grabCleanPage. The test essentially stresses the ledger page cache mechanism by creating a large number of ledgers.
