Hbase Mapreduce Job using wrong table name in maper

Question

I have some crawled content in Hbase table (via Nutch). I have written to process a table and output its stats into a new table via mapreduce job. Following is the code snippet of MR job.

NutchJob job = NutchJob.getInstance(getConf(), "customJob");

// === Map ===
DataStore<String, WebPage> pageStore = StorageUtils.createWebStore(
    job.getConfiguration(), String.class, WebPage.class);
Query<String, WebPage> query = pageStore.newQuery();
query.setFields(StorageUtils.toStringArray(FIELDS)); // Note: pages without
                                                     // these fields are
                                                     // skipped
LOG.info( "Table before mapper: " + job.getConfiguration().get(Nutch.CRAWL_ID_KEY ) );

GoraMapper.initMapperJob(job, pageStore, Text.class, WebPage.class,
        TableCopy.Mapper2.class, true);

job.setNumReduceTasks(1);


job.getConfiguration().set(Nutch.CRAWL_ID_KEY, "txt" );
LOG.info( "Table before reducer: " + job.getConfiguration().get(Nutch.CRAWL_ID_KEY ) );

DataStore<String, WebPage> hostStore = StorageUtils.createWebStore(
        job.getConfiguration(), String.class, WebPage.class);


GoraReducer.initReducerJob(job, hostStore, MarkerUpdateReducer2.class);

job.waitForCompletion(true);

There are two tables one given at common line and second is hard coded ("txt") in this case. My intention is to create reducer datastore with some new table name so that I can store data there. But what happens is that in mapper the table "txt" is processed and as there is not data in this table, job do noting. Following is the log snippet

I have printed table name in setup method. It is shown text as given in above logs "map table: txt". Actual table ins "a"
