hcli [--option] support [checkDisks [--option] ] | [configureDisk [--option]] | [install rpm name | patch name [--option]] | [manager_config [--option]] | [rebalance [--option]] | [tune_coresidence] [--option]]] | [[--nolog] support [setpgpass password ]Parameters
- hcli support checkDisks [OPTIONS]
- Report status of disk drives in the cluster.
Option Description --node Reports disks from the local node only (default on datanodes) --system Reports disks from the entire cluster (default on master nodes) --json Reports all data in JSON format --failed Reports only disks with abnormal status Exit code 0 indicates the command succeeded; exit code 1 if the report failed. - hcli support configureDisk [--check]
- Configure, format, and prepare data node disk configurations for use after a disk drive replacement.
- Create vdisks on RAID controller
- Create filesystem and disk label if not present
- Update mount options in /etc/fstab
- Mount data drive filesystems
- Use the --check option to check that the data node disks are correctly configured and labeled. No configuration changes are made.
- Exit code 0 indicates the command succeeded; exit code 1 indicates the number of nodes on which the command failed
- hcli support install --rpm name | --patch name [--master | --data | --edge | --all | --dry-run ]
- Install RPMs and patches on nodes in the cluster. Either the RPM and name or the patch and name are required.
- -r | --rpm name Installs the specified RPM file.
- -p | --patch name Installs the specified patch file.
Option Description -m | --master Installs on master nodes -d | --data Installs on data nodes -e | --edge Installs on edge nodes -a | --all Installs on all nodes -n | --dry-run Tests the installation but does not make changes Exit code 0 indicates the command succeeded; exit code 1 indicates the command failed. - hcli support manager_config [OPTION]
- Modify Ambari
related settings.
Option Description --port port number Update the port number used to connect to Ambari . --host= host fqdn Update the hostname used to connect to Ambari . --password A password prompt displays to update the Ambari administrator password. Exit code 0 indicates the Ambari setting updated successfully; exit code 1 indicates the setting could not be updated. - hcli support rebalance
- Adjust parameters to enable high-priority HDFS rebalancing after expanding or contracting a cluster.
- Waits until rebalance is complete before exiting.
- Exit code 0 indicates the rebalance succeeded; exit code 1 if the HDFS could not be rebalanced.
- hcli [--nolog] support setpgpass password
- Change the password on postgres and update postgres/.pgpass files on the postgres nodes.Use the --nolog option to avoid recording passwords in debugging logs.Exit code 0 indicates the command succeeded; exit code 1 indicates the command failed.
- hcli support tune_coresidence [--node | --help]
- Tune data nodes in the cluster for coresidence configuration.
Option Description -n | --node FQDN Specifies the fully-qualified domain name of a single node that is tuned to the coresidence configuration. -n FQDN-NODE1 -n FQDN-NODE2 Specifies the fully-qualified domain names of all nodes that are tuned to the coresidence configuration. -h | --help Shows help for this command. Exit code 0 indicates that the tuning for coresidence configuration has completed; exit code 1 indicates an exception has occurred.
