The issue was with using wrong solr version.I was using Solr version 7.5. Sitecore version 9 is compatible only with the versions 6.6.1, 6.6.2, 6.6.3.I found the compatibility table at https://kb.sitecore.net/articles/227897. I have uninstalled Solr 7.5 and installed 6.6.2 and no longer see the issue.
