Reply To: Ambari Server After Changing Host Names and IP

This appears to work in postgresql for the sandbox. Simply update the columns in the listed tables at the bottom of this post, restart, and you should be good to go. Not supported, but it works…

try {
Class.forName("org.postgresql.Driver");
Connection con = DriverManager.getConnection("jdbc:postgresql:ambari","steve","welcome");

DatabaseMetaData md = con.getMetaData();
ResultSet rs = md.getTables("ambari", "ambari", "%", null);
while (rs.next()) {
ResultSet rsc = md.getColumns("ambari","ambari",rs.getString(3),null);
int i = 0;
while (rsc.next()) {
if (rsc.getString("TYPE_NAME").equals("character varying")
|| rsc.getString("TYPE_NAME").equals("text")
|| rsc.getString("TYPE_NAME").equals("varchar")) {
try {
Statement stm = con.createStatement();
ResultSet rst = stm.executeQuery("select " + rsc.getString("COLUMN_NAME") +
" from ambari." + rs.getString(3) +
" where " + rsc.getString("COLUMN_NAME") + " like '%hortonworks.com%'");
while (rst.next()) {
System.out.printf("%-40s %s\n", rs.getString(3), rsc.getString("COLUMN_NAME"));
}
}
catch (Exception e1) {
//e1.printStackTrace();
}
}
}
}
}
catch (Exception ex) {
ex.printStackTrace();
}
}
}
