Install impala1.4.1 using the RMP package

Install the Impala dependency package first
Add repo using Yum installation
sudo wget-o/etc/yum.repos.d/bigtop.repo Http://www.apache.org/dist/bigtop/bigtop-0.7.0/repos/centos5/bigtop.repo
sudo yum install bigtop-utils


The version of CDH that Hadoop uses for 5.1.2 is required for the Impala version 1.4.1
Download the RMP package from the Cloudera warehouse
impala1.4.1 Warehouse Address http://archive.cloudera.com/cdh5/redhat/5/x86_64/cdh/5.1.2/RPMS/x86_64/
Install the State-store and catalog services on the Namenode, install the Impala-server service on the Datanode, and the Impala Basic service is installed on each machine
You must use--force--nodeps when you install the Impala Base service because the RMP package checks the dependent environment
sudo rpm-ivh impala-1.4.1+cdh5.1.2+0-1.cdh5.1.2.p0.3.el5.x86_64.rpm--force--nodeps
Copy or soft-link core-site.xml,hdfs-site.xml,hbase-stie.xml to Impala's conf directory after each node is loaded with the corresponding service
sudo ln-s $HADOOP _conf_dir/core-site.xml/etc/impala/conf/core-site.xml
sudo ln-s $HADOOP _conf_dir/hdfs-site.xml/etc/impala/conf/hdfs-site.xml
sudo ln-s $HBASE _conf_dir/hbase-site.xml/etc/impala/conf/hbase-site.xml
Because Impala needs to use hive's metadata, it's namenode to copy Hive-site.xml.


Because Hadoop and other components are installed with a tar package, and Impala is installed with the RPM package, the jar link created by Impala is not valid, so remove the invalid link manually and then re-add the required jar package

Impala default installation directory is/usr/lib/impala,jar package address is/usr/lib/impala/lib/

The

Jar package can be downloaded from here https://repository.cloudera.com/content/groups/cloudera-repos/because Impala does not loop to add a directory when it starts loading the jar/usr/lib /impala/lib/all the files under the file, but in the boot file to write dead jar package name, so add jar package when you want to rename, or do a soft link
Impala also needs HADOOP's libhadoop.so and libhdfs.so, which write so files can be from $hadoop_home/src/hadoop-hdfs-project/hadoop-hdfs/src/build/ target/usr/local/lib/and $hadoop_home/lib/native/both directories get to
