Before installing, you check the below activities,it may help in resolving your issue,
1. Check the network connectivity with your local Repo server.
2. Check whether your repo files are present under
/etc/yum.repos.d directory.
3. Remove old yum cache from system by running following commands. # rm -fr /var/cache/yum/*
# yum clean all 4. Check if you can list the valid repositories. # yum repolist 5. Check the package availability through yum. # yum list | grep mysql-connector-java

none inf none inf 1 0 0 /user/ruser/quota
[hdfs@XXXX ~]$ hdfs dfsadmin -setSpaceQuota 40g /user/ruser/quota

@Harold Allen Badilla In your command, you are using mysql database connection string i.e "--connect jdbc:mysql://XXXXX" with "--driver" option with value as SQL Server driver class name. So your connection string should be changed as SQL Server format. Proper command syntax will look something like this, sqoop import --connect --connect "jdbc:sqlserver://<Server_Host>:<Server_Port>;databaseName=<DB_Name>" \
--driver com.microsoft.sqlserver.jdbc.SQLServerDriver \
--username XXXXXXXXXXXX --password XXXXXXXXXXX \
--table dbo.knal \
--target-dir /tmp/db0-customer

To check Namenode Safe mode status, Login to Namenode host and issue the below command, [user@NNhost1 ~]$ hdfs dfsadmin -safemode get
Safe mode is OFF in NNhost1/10.X.X.X:8020
Safe mode is OFF in NNhost2/10.X.X.X:8020
If Safe mode is turned ON, please issue the below command to leave from safemode.
[user@NNhost1 ~]$ hdfs dfsadmin -safemode leave
