Does that help Wrote my own implementation of JdbcInsertBolt,JdbcClient, and JdbcMapper
Mapper relevant code:
code :
 else if(getJavaType(columnSqlType).equals(Array.class)) {
            String[] value = (String[]) tuple.getValueByField(columnName);
            columns.add(new Column(columnName, PDataType.instantiatePhoenixArray(PDataType.arrayBaseType(PVarcharArray.INSTANCE),value) , columnSqlType));
 else if (columnJavaType.equals(Array.class)) {
            preparedStatement.setArray(index, (PhoenixArray) column.getVal());

Which copy of storm.yaml file in the storm cluster is used by storm nimbus and supervisor daemons?

Which copy of storm.yaml file in the storm cluster is used by storm nimbus and supervisor daemons?

wish help you to fix your issue Each daemon uses its local copy of storm.yaml. Thus, Nimbus and Supervisor share the same file, if they run on the same machine. Worker JVM always run on the same machine as their corresponding supervisor and thus, always share the same file.
Hence, if you only change Nimbus related parameters, there is no need to distribute storm.yaml over all supervisor nodes. If you change Supervisor parameters and want all Supervisors to "see" the same new configuration, you will need to distribute the file over all nodes (you need to restart the Supervisors, too).

I wish this help you I have the following SQL expression: , I think there are multiple ways you can do this:
code :
select * from ((query1 inner join query2 on column_names) inner join query3 on column_names) 
(query1 where exists (query2 where exists (query3)) )
(query1 where column_name in (query2 where column_name in (query3)) )

How to write c++ spout/bolt on Storm and Thrift usage in Storm

Hope this helps I'm not sure if I'm understand your question correctly -- in my understanding you're asking Is it possible [without the Shebolt hack] to use Storm [with Thrift as comm protocol] with C++-written bolts and with C++ as the language that creates the topology.
Because of the lack of other answers to this question and based on my own research I assume there is no finished, usable implementation for your problem.
