800-327-8611Structured WiringIndustrial Quality Installer Drill Bits - Wire InstallationINSTALLATION TOOLSThe Semi Flexible Masonry DrillBit is preferred when straight alignment between the drill chuck andcutting point is desired. The stiffer shaft allows for extra torquetransmission from the power tool to the cutting point.B & A’s non-carbide Bell hangerdrill bits are specifically designed for small wire installationapplications. Telephone, security alarm, fire alarm, cable, networkinstallers, electricians, and other professionals all use these uniquedrill bits to drill holes through walls, studs and other obstacles tofish the small wire back through the drilled hole with ease. HDBH seriesbits are designed for drilling through wood, plaster or drywall.High Speed steel (HSS) bits are the mostcommonly used bit for drilling thru metal, aluminum, brass, andhardwoods.

.This section contains information on administering the cluster and MapR-DB, configuring Gateways, and configuring andmanaging particular aspects of the MapR security infrastructure.This section describes how to manage the nodes and services that make up a cluster.This section describes how to monitor the health and performance of a MapR cluster.A MapR gateway mediates one-way communication between a source MapR cluster and a destination cluster. MapR-DB tablesand MapR Streams streams can be replicated.Administration of the MapR-DB is done primarily via the commmand line (maprcli) or with the MapR Control System (MCS).Regardless of whether the MapR-DB table is used for binary files or JSON documents, the same types of commands are usedwith slightly different parameter options. MapR-DB administration is associated with tables, columns and column families,and table regions.Describes tasks for configuring MapR security, managing secure clusters, and administering auditing.This section contains in-depth reference information for the administrator.This section provides information about the MapR command API. Most commands can be run on the command-line interface (CLI),or by making REST requests programmatically or in a browser.This section contains information about various scripts and utilities.This section contains reference information about various configuration files.The pages in this section provide details about all of the types of alarms.This section provides information associated the MapR environment.This section contains defintions for commonly used terms in MapR Converged Data Platform environments. Go to the Manage Services pane of the Node Properties View to check if Drill isrunning. Warden tries three times to restart Drill automatically every 30 minutes (bydefault).
This 30 minute interval can be reconfigured using the parameterservices.retryinterval.time.sec in the warden.conffile.If warden successfully restarts Drill, the alarm is cleared. If warden is unable torestart Drill, review the Drill log files, drillbit.out anddrillbit.log, located in the/opt/mapr/drill/drill-/logs directory to identify whyDrill stopped running.
Once you have identified and resolved the issue, run thefollowing command to restart Drill on thenode(s): $ maprcli node services -name drill-bits -action restart -nodes If the attempt to restart Drill on the node (s) fails, contact MapR technicalsupport.
