5. Right click on mapreduce location beside consol in eclipse and click on new hadoop location.

6. On define hadoop location prompt fill
   location name=111.111.1.111
   map/reduce master    dfs master
   host=111.111.1.111

How to auto re-launch a YARN Application Master on a failure.

1)Use Case: The fundamental idea of Hadoop2 (Map-Reduce + Yarn) is to split up the two major functionalities of the JobTracker, resource management and job scheduling/monitoring, into separate daemons. The idea is to have a global ResourceManager ( RM ) and per-application ApplicationMaster ( AM ). An application is either a single job in the classical sense of Map-Reduce jobs or a DAG of jobs. The ResourceManager and per-node slave, the NodeManager ( NM ), form the data-computation framework. The ResourceManager is the ultimate authority that arbitrates resources among all the applications in the system. The per-application ApplicationMaster is, in effect, a framework specific library and is tasked with negotiating resources from the ResourceManager and working with the NodeManager(s) to execute and monitor the tasks. The ResourceManager has two main components: 1. Scheduler: is responsible for allocating resources to the various running applications. 2. Appl

Read JSON File in Cassandra

Image
INSERT/Load Json data File in Cassandra (3.0+) table Requirement: Create Cassandra table where we can load json data into it. Here some of the column name is separated by space(like 'a b'). Load JSON file into the table. Challenge:  Cassandra support only 'CSV file' load in Table(As per my understanding and searched till now) by using 'COPY' command but not 'JSON' file. Resolution: As per the Cassandra document page, Cassandra supports CSV record level insert and file level insert both operation but for JSON it only support Record level insert by following command: cqlsh> INSERT INTO keyspace1.table1 JSON '{   "id" : "12",    "DB" : "Cassandra",    "ops" : "Insert",   "Project" : "Hadoop" }'; So If we want to insert whole file in the table then we need to loop for each object in JSON file and need to call insert query every tim
