The hive build is divided into three modes: 1, embedded,2, local,3, remote serverIn this case, the main configuration is the 3rd mode: remote Server modeMy environment is a total of three virtual machines: HOST0,HOST2,HOST3In remote server mode, the Host0:hive-server2Host2:hive-metastoreHost3:mysql Server1, respectively in the Host0,host2 and Host3 installed

Hive is often used in work, and hive can be used more efficiently with hvie configuration parameters. Hive option: Hive-F script. hql: read from the script. hql file and execute hql. Hive-e 'select * From XXX': Specifies the hql to be executed when

The partition table created in hive has no complex partition type (range partition, list partition, hash partition, mixed partition, etc.). A partitioned column is also not an actual field in a table, but one or more pseudo-columns. This means that the information and data of the partition column are not actually saved in the data file of the table. The following statement creates a simple partition table: CREATE TABLE Partition_test (member_id strin

To better use hive, I took out the security section of Programming hive and translated it.Hive also supports quite a few rights management functions to meet the general Data Warehouse usage.Hive configures the default permissions for new files by a default setting.XML code property> name>hive.files.umask.valuename> value>0002value> description>the dfs.umask value for the

First, Hive Overview and Architecture What is 1.Hive? (1). Open Source by Facebook, originally used to solve the massive structural log data statistics problem(2). is a data warehouse built on top of Hadoop(3). Hive defines a language similar to SQL query: HQL (very similar to SQL statements in MySQL, and extended at the same time)(4). Typically used for offlin

Hive is now the most common and inexpensive solution for building data warehouses in the Big data era, although there are also other rising stars such as Impala, but the status of hive is not yet shaken in terms of functionality and stability.In fact, this blog is mainly to talk about SMB join, join is the most core part of the whole mr/hive, is the part of each

Recently in the data analysis of a traffic flow, the demand is for a huge amount of urban traffic data, need to use MapReduce cleaning after importing into hbase storage, and then using the Hive External table associated with hbase, hbase data query, statistical analysis, Save the analysis results in a hive table, and finally use Sqoop to import the data from that table into MySQL. The whole process is prob
