• We have few Flume based jobs which are loading data from KAFKA to HDFS
• We are using load balancing by HA configuration. We have many data node for Hadoop yarn cluster and two NameNode. We are using Caloudera CMF to support any job failure and monitoring hive,impal,hdfs,yarn. We are using Sentry and ACLs for hive and HDFS security management .We are using HUE to look HIVE, IMPALA, HDFS and Sentry management
• Working as Hadoop admin to resolve Hadoop issue support for production jobs.
• I am doing daily on job creation on Talend using their component like Hive,Impala,HDFS with security keytab and principle configuration for open HDFS and hive connection to load file data into HDFS form ingestion server(Linux) .Since we get mainframe files from source so required to parse this raw file by using Jrecord API with Talend java component and need to voltaziged PII/PCI data by using HP voltage simple java api. File come with average sized 20 GB(sometimes around 40GB) from each platform like north,south etc.we are storing file into hdfs as parquet format.
