Make corrections to HFile path To estimate the row count for an HBase table, the HFiles are accessed directly from the HDFS file system. When the Trafodion name of the table includes a delimited id, the quotes must not be included in the node of the HDFS path representing the qualified table name. In addition, the hbase.rootdir property in hbase-site.xml may consist solely of a path rather than a full URL. It was previously assumed that a full URL would be present, and the value of the property was used to construct a java.net.URI object. When a string consisting of only a file path is passed to the URI constructor, a NullPointerException is thrown (instead of the expected URISyntaxException), causing the path we construct to the HFile to be incorrect. The code was changed to utilize either a file path or a valid URI as the value of the property.
