- * If cluster version is the same as default, update option to current
drillbit version.
+ * If cluster version is the same as default, updates option to current
drillbit version.
+ * Since getOption and setOption are separate calls, raise condition
might occur
+ * when several drillbits are registering at the same time.
+ * It is assumed that the first drillbit in cluster sets cluster version
+ * but when the raise condition occurs, it might be the second or the
third etc.
+ * This behaviour does not impose significant impact, since the main
goal is to detect mismatching versions.
