Method Detail

stop

void stop(boolean cancel)

Stops IGFS cleaning all used resources.

Parameters:

cancel - Cancellation flag.

context

IgfsContext context()

Returns:

IGFS context.

globalSpace

IgfsStatus globalSpace()
                throws IgniteCheckedException

Gets global space counters.

Returns:

Tuple in which first component is used space on all nodes, second is available space on all nodes.

Throws:

IgniteCheckedException - If task execution failed.

globalSampling

void globalSampling(@Nullable
                    @Nullable Boolean val)
             throws IgniteCheckedException

Enables, disables or clears sampling flag.

Parameters:

val - True to turn on sampling, false to turn it off, null to clear sampling state.

Throws:

IgniteCheckedException - If failed.

globalSampling

@Nullable
@Nullable Boolean globalSampling()

Get sampling state.

Returns:

True in case sampling is enabled, false otherwise, or null in case sampling flag is not set.

groupBlockSize

long groupBlockSize()

Gets group block size, i.e. block size multiplied by group size in affinity mapper.

Returns:

Group block size.

clientLogDirectory

@Nullable
@Nullable String clientLogDirectory()

Gets client file system log directory.

Returns:

Client file system log directory or null in case no client connections have been created yet.

clientLogDirectory

                     boolean primary)

Whether this path is excluded from evictions.

Parameters:

path - Path.

primary - Whether the mode is PRIMARY.

Returns:

True if path is excluded from evictions.

nextAffinityKey

IgniteUuid nextAffinityKey()

Get next affinity key.

Returns:

Next affinity key.

isProxy

boolean isProxy(URI path)

Check whether the given path is proxy path.

Parameters:

path - Path.

Returns:

True if proxy.

asSecondary

IgfsSecondaryFileSystem asSecondary()
