Dave Marion commented on ACCUMULO-3645:
---------------------------------------
I don't see how this is a bug. It would appear to be by design or optimization
that iterators do not run on tables that have no data.
Also, I'm not sold on the idea of using iterators on an empty table to execute
business logic or stored procedures, but if this is what we are going to do
then I suggest:
1. Creating a new issue of type "New Feature" that describes the approach
2. Make this and all other supporting issues a subtask under the new top level
issue.
> Iterators not run at compaction when tablets are empty
> ------------------------------------------------------
>
> Key: ACCUMULO-3645
> URL: https://issues.apache.org/jira/browse/ACCUMULO-3645
> Project: Accumulo
> Issue Type: Bug
> Components: client, mini, tserver
> Affects Versions: 1.6.1
> Environment: Ubuntu 14.04, Accumulo 1.6.1, Hadoop 2.6.0, Zookeeper
> 3.4.6
> Reporter: Dylan Hutchison
>
> When an iterator is configured to run during a one-time manual major
> compaction on a tablet that is empty, the iterator never runs. It seems as if
> Accumulo never constructs the SKVI stack at all, because it tries to optimize
> by eliminating "unnecessary" tablet compactions. Also true of MiniAccumulo.
> This is bad for "generator" iterators that emit keys (in sorted order) not
> present in the tablet's data. They never have a chance to run.
> A workaround is for the client to insert "dummy data" into the tablets he
> wants to compact, before starting a compaction with "generator" iterators.
> Note that *any* data is sufficient, even delete keys, to ensure the SKVI
> stack is built and run through.
> Test file:
> [InjectTest|https://github.com/Accla/d4m_api_java/blob/master/src/test/java/edu/mit/ll/graphulo/InjectTest.java]
> * method {{testInjectOnCompact_Empty}} fails because no data is in the tablets
> * method {{testInjectOnCompact}} passes because data is written into the
> tablets before initiating compaction.
> Two logs follow. Both have a
> [DebugIterator|https://accumulo.apache.org/1.6/apidocs/org/apache/accumulo/core/iterators/DebugIterator.html]
> set after an
> [InjectIterator|https://github.com/Accla/d4m_api_java/blob/master/src/main/java/edu/mit/ll/graphulo/InjectIterator.java],
> an SKVI which "generates" hard-coded entries. The root user scans the table
> after flush and compact.
