In this post, we’ll go over the configuration changes needed to make HDFS client talk to ADLS, and commands to copy HBase table snapshots from HDFS to ADLS and vice-versa. Introduction “The Azure Data Lake store is an Apache Hadoop file system compatible with Hadoop Distributed File System (HDFS) and works with the Hadoop ecosystem.” The zip archive is referred to as a client configuration file. Each archive contains the set of configuration files needed to access the service: for example, the MapReduce client configuration file contains copies of core-site.xml, hadoop-env.sh, hdfs-site.xml, log4j.properties, and mapred-site.xml. HDFS is an append-only file system. As the data comes into the NFS gateway, it has to write that 5GB file down to the local Linux file system that's read/write, so oftentimes that's EXT4 or XFS. Now I've got this extra hop where I have to write data down. I've got to make sure there's enough space in /tmp, because that's actually where it This entry was posted in Hive and tagged apache commons log format with examples for download Apache Hive regEx serde use cases for weblogs Example Use case of Apache Common Log File Parsing in Hive Example Use case of Combined Log File Parsing in Hive hive create table row format serde example hive regexserde example with serdeproperties hive regular expression example hive regular expression
