Method Detail

setSessionOption

public static void setSessionOption(DrillClient drillClient,
                                    String option,
                                    String value)

setControls

public static void setControls(DrillClient drillClient,
                               String controls)

setControls

public static void setControls(UserSession session,
                               String controls)

validateControlsString

public static void validateControlsString(String controls)

createException

public static String createException(Class<?> siteClass,
                                     String desc,
                                     int nSkip,
                                     int nFire,
                                     Class<? extends Throwable> exceptionClass)

Create a single exception injection. Note this format is not directly accepted by the injection mechanism. Use the Controls to build exceptions.

createExceptionOnBit

public static String createExceptionOnBit(Class<?> siteClass,
                                          String desc,
                                          int nSkip,
                                          int nFire,
                                          Class<? extends Throwable> exceptionClass,
                                          CoordinationProtos.DrillbitEndpoint endpoint)

Create a single exception injection on a specific bit. Note this format is not directly accepted by the injection mechanism. Use the Controls to build exceptions.

createPause

public static String createPause(Class<?> siteClass,
                                 String desc,
                                 int nSkip)

Create a pause injection. Note this format is not directly accepted by the injection mechanism. Use the Controls to build exceptions.

createTimedPause

public static String createTimedPause(Class<?> siteClass,
                                      String desc,
