> Key: ACCUMULO-2911
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2911
> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.5.0
> Reporter: David Medinets
> Priority: Trivial
>
> Problem:
> I can use a custom iterator using the setiter command but the same iterator
> does not work using the setscaniter or setshelliter commands.
> References:

> Description:
> I am using my https://github.com/medined/D4M_Schema project to start
> Accumulo. So the environment that I am using can be duplicated exactly if
> needed. I am using
> Accumulo: 1.5.0
> Hadoop: 1.2.1
> The classpath settings in accumulo-site.xml are the following (which I think
> are the default):
> <property>
> <name>general.classpaths</name>
> <value>
> $ACCUMULO_HOME/server/target/classes/,
> $ACCUMULO_HOME/core/target/classes/,
> $ACCUMULO_HOME/start/target/classes/,

> I can load my iterator using setiter but not with setscaniter or setshelliter.
> Here is my do-nothing iterator:
> public class MyIterator extends WrappingIterator implements OptionDescriber {
> @Override
> public IteratorOptions describeOptions() {
> String name = "dummy";
> String description = "Dummy Description";
> Map<String, String> namedOptions = new HashMap<String, String>();
> List<String> unnamedOptionDescriptions = null;
> return new IteratorOptions(name, description, namedOptions,
> unnamedOptionDescriptions);
> }
> @Override
> public boolean validateOptions(Map<String, String> options) {
> return true;
> }
>
> }
> I copy the jar file out to HDFS:
> hadoop fs -mkdir /user/vagrant/d4m/classpath
> hadoop fs -put /vagrant/schema/target/d4m_schema-0.0.1-SNAPSHOT.jar
> /user/vagrant/classpath
> I set the table-specific classpath context:
> createtable atest
> table atest
> insert row cf cq value
> config -s
> general.vfs.context.classpath.d4m=hdfs://affy-master:9000/user/vagrant/classpath
> config -t atest -s table.classpath.context=d4m
> Now I can configure the iterator and scan over the single row without a
> problem:
> setiter -n MyIterator -p 10 -scan -minc -majc -class
> com.codebits.d4m.iterator.MyIterator
> scan
> deleteiter -n MyIterator -scan -minc -majc
> However, the setscaniter commands fails:
> root@instance atest> setscaniter -n MyIterator -p 10 -class
> com.codebits.d4m.iterator.MyIterator
> 2014-06-15 02:54:14,098 [shell.Shell] WARN : Deprecated, use setshelliter
> Dummy Description
> 2014-06-15 02:54:14,126 [shell.Shell] ERROR:
> org.apache.accumulo.core.util.shell.ShellCommandException: Command could not
> be initialized (Unable to load com.codebits.d4m.iterator.MyIterator)
> As does the setshelliter:
> root@instance atest> setshelliter -pn d4m -n MyIterator -p 10 -class
> com.codebits.d4m.iterator.MyIterator
> Dummy Description
> 2014-06-15 02:55:07,025 [shell.Shell] ERROR:
> org.apache.accumulo.core.util.shell.ShellCommandException: Command could not

> I don't see any messages in the log files.
