Apache HBase

Deepak Vohra · Apress eBooks · 2016

Apache HBase is a distributed, scalable database designed for Apache Hadoop. HBase is a flexible format NoSQL database. HBase has three main components: HMaster, ZooKeeper, and RegionServers. The HMaster handles the DDL (create and delete) operations. The ZooKeeper is a distributed coordination service for an HBase cluster. RegionServers manage HBase table data and serve client requests. An HBase table is mapped to one or more regions using row key ranges to split the HBase table. More regions are used as a table grows. HMaster manages region assignment. Regions are stored in RegionServers, which serve PUT/GET requests from a client. Each RegionServer is collocated with a DataNode on HDFS. HBase table data is stored in the HDFS. The metadata for the Region->RegionServer mapping is kept in a metatable, which is stored on the ZooKeeper. A client request is first sent to the ZooKeeper, which provides the RegionServer the locations for the requested data. Subsequently, the client GETs/PUTs data directly on a RegionServer. The HBase architecture is illustrated in Figure 4-1.

Using Apache HBase

Deepak Vohra · Apress eBooks · 2015

Apache HBase is the Apache Hadoop database. Apache HBase is based on the wide column data store model with a table as the unit of storage. A table consists of one or more column families. Apache HBase is a schema-free NoSQL database. HBase stores data in the HDFS by default. In this chapter we shall use a Docker image to run Apache HBase in a Docker container. We shall use the svds/cdh Docker image, which we introduced in the Chapter 8 .

HBase region server’s architecture.

<div><p>The massive amount of vehicle plate data generated by intelligent transportation systems is widely used in the field of urban transportation information system construction and has a high scientific research and application value. The adoption of big data platforms to properly preserve, process, and exploit these valuable data resources has become a hot research area in recent years. To address the problems of implementing complex multi-conditional comprehensive query functions and flexible data applications in the key–value database storage environment of a big data platform, this paper proposes a data access model based on the jump hash consistency algorithm. Algorithms such as data slice storage and multi-threaded sliding window parallel reading are used to realize evenly distributed storage and fast reading of massive time-series data on clustered data nodes. A comparative analysis of data distribution uniformity and retrieval efficiency shows that the model can effectively avoid generating the cluster hotspot problem, support comprehensive analysis queries with various complex conditions, and maintain high query efficiency by precisely positioning the data storage range and utilizing parallel scan reading.</p></div>

Using the HBase Shell

Deepak Vohra · Apress eBooks · 2016

All names in the Apache HBase shell should be quoted, such as the table name, row key, and column name. Constants don’t need to be quoted. Successful HBase commands return an exit code of 0. But a non-0 exit status does not necessarily indicate failure and could indicate other issues, such as loss of connectivity.

Apache HBase and HDFS

Deepak Vohra · Apress eBooks · 2016

HBase runs on HDFS as the underlying filesysystem and benefits from HDFS features such as data reliability, scalability, and replication. HBase stores data as StoreFiles (HFiles) on the HDFS datanodes. HFile represents the file format for HBase. HFile is an HBase-specific file format based on the TFile binary file format. A StoreFile can be considered a lightweight wrapper around the HFile. HBase also stores the write-ahead logs (WALs), which store data before it is written to HFiles on HDFS. HBase is a HDFS client and makes use of the DFSClient class, references to which appear in the HBase client log messages and HBase logs, to connect to NameNode to get block locations for datanode blocks and add data to the datanode blocks. HBase leverages the fault tolerance provided by the Hadoop File System (HDFS). HBase requires some configuration at the client side (HBase) and the server side (HDFS).
