tothesuccessfulinstallationofHadoop.Now'snotthetimetogetfrustrated,
but to follow what the logs tell you and make the adjustments necessary to
try the installation again. Here we will walk you through where to find the
information you'll need to be successful.
Installation Logs
IfyouhaveanyfailuresduringtheinstallationofHDP,checktheinstallation
log files located at
C:\HadoopInstallFiles
. Specifically, you'll want the
file located at
C:\HadoopInstallFiles\HadoopSetupTools\hdp-1.3.0.0.winpkg.install.txt
.
If the package did not install correctly, details in this file can help guide
you in fixing the solution. Generally, the issues revolve around not paying
attention to the details of the installation instructions, such as creating the
appropriate environmental variables, making all the changes in the
configuration file, or disabling the firewall. If the error seems to involve
one of these steps in the pre-installation phase, go back and double-check
that you did everything correctly. Make sure that all paths and names are
exactly as they are supposed to be, because this is where most people make
mistakes.
Individual Service Logs
If you had a successful installation of HDP but are having trouble starting
the services, look into the product log directory that was specified in the
clusterproperties.txt
fileduringinstallation. Recallthattheexample
in this topic had them located at
C:\hadoop\logs
.
Each one of the services has a separate folder. Each folder has multiple files
in it, and you might have to open a few to determine the correct one for a
particular problem. For example, if you are having a problem starting the
Hive service, you navigate to the
C:\hadoop\logs\hive\hive.txt
file.
