SOLR has issues if impersonating principal has a hyphen in its name

Any Kerberos principal which contains characters that do not match regex "[a-zA-Z_][a-zA-Z0-9_]*" cannot be used as an impersonating user in Solr. This may affect HUE and KNOX access to Solr, as the principals for these services are configured as Solr proxy users by default. This issue is resolved.
