I have faced same problem, but its resolved … now
During cluster install, DataNode fails to install with the following error:
<pre class=”programlisting”>resource_management.core.exceptions.
Fail: Execution of ‘/usr/bin/yum -d 0 -e 0 -y install snappy-devel’ returned 1.
Error: Package: snappy-devel-1.0.5-1.el6.x86_64 (HDP-UTILS-1.1.0.20)
Requires: snappy(x86-64) = 1.0.5-1.el6
Installed: snappy-1.1.0-3.el7.x86_64 (@anaconda/7.1)
snappy(x86-64) = 1.1.0-3.el7
Available: snappy-1.0.5-1.el6.x86_64 (HDP-UTILS-1.1.0.20)
snappy(x86-64) = 1.0.5-1.el6
Hadoop requires the snappy-devel package that is a lower version that what is on the machine already. Run the following on the host and retry.
<pre class=”programlisting”>yum remove snappy
yum install snappy-devel
Now this problem will resolved.
